Crosby XXX Third Version

http://www.sturmgewehr.com/dalbert/MGBoards/Mags/Crosby%20XXX%20Third%20Version_Web.JPG

 

There are four different versions of Seymour Products XXX magazines. With the exception of the second version, which is absent of punctuation marks, the collector should ignore the presence or absence of punctuation to determine versions. The first, third and fourth versions can be found with any or all of their punctuation missing, most likely due to these very small parts of the die wearing or breaking. An example of this is shown in the following pictures of two different First Version magazines. Both have the comma on the second line, but one has the periods at the end of both lines and the other does not. This is not a different version, just worn dies.

BLANK XX MAGAZINES

 

There are three different blank XX magazines that have been identified. The Sparks-Withington is the easiest of the three to recognize because the observation holes are placed differently from the other two. However, since many magazines have been disassembled and reassembled in their lives, usually in large batches where the components are unlikely to get matched up again, great care needs to be taken in declaring a particular blank magazine as all original. The following pictures show unique characteristics of the three blank magazines.

 

Since an A-O Blank magazine was not available to be photographed, here is a description of the unique characteristics of that magazine. First, the radius of the front of the feed lips of the A-O Blank is much more gradual than the sharper radius of the Colt Blank. The A-O radius is the same as versions three and five of the A-O XX magazines. Second, the tool marks on the inside of the backstrap and its shoulders are the same as those on A-O version five. The Colt Blank tool marks are not the same, but you may need both in front of you to make the identification easier.

 

All A-O followers do not have a stress relief hole punched just above the follower tab, as shown in the example below. The other manufacturers

punched a hole in various locations just above the follower tab as can be seen in the Colt Era and Sparks-Withington examples below.

UNIQUE MAGAZINE FEATURES

 

There are three kinds of floorplates found on Thompson magazines. The flat, plain floorplate is standard for all but one of the XX magazines and two of the XXX magazines. The beveled floorplate is found only on Sparks-Withington magazines, all versions. It was apparently designed by

Sparks-Withington to make it easier to insert the floorplate into the magazine body.

 

The dimpled floorplate is unique to Seymour XXX magazines. It has been observed on both third and fourth versions of magazines in the original

wrap, but it is unknown exactly when it was introduced or whether its use alternated through the versions. So far all fourth version magazines in the wrap have been observed with the dimpled floorplate. If anyone in the Thompson collecting community has second or first version Seymours still in the wrap with the dimpled floorplate, please contact TSMG28 on this board.

The Israelis inherited a number of Thompson magazines from the British, mostly the 20-round XX version. They stamped two marks on each, though the depth and location of the stamps varies considerably. Most of these magazines have also been green parkerized, but examples can be found that are still blued. Some magazines also have the witness holes soldered as modified by Australians/British armorers in the desert of North Africa during WWII.

 

The mark on the right side is the tradition "Tza'dik" sign. That's the first letter of the word "Tsa'va" which means Army. This sign (in various forms) is supposed to appear on anything owned by the Israeli military. The mark on the left side is believed to be the letter "Chet" which is the first letter of the word "Chi'mush", which stands for armament. That's the division that handles all the purchases, processes and logistics behind weaponry.

The "V for Victory" sign was added to some XXX magazines during 1943 as an encouragement at a time when the war effort was not going well for the U.S. This V can be found on both Crosby and Seymour XXX magazines.

The first batch of Crosby XXX magazines had a little problem when they tried to use them in the new M1 Thompson. The front of the feed lips stuck out too far from the magazine body and created an interference that caused feed problems in the M1 model. The Augusta Arsenal came up with a modification that allowed these magazines to be used, essentially grinding 0.060" from the front of the feed lips. That modification can be found on the picture below.

THE OTHER GUYS...

 

BSA

 

These magazines were made for the European style (rifle-like) Thompson submachine guns manufactured by Birmingham Small Arms, Ltd., first in 1926 and later in 1929. These magazines exist in four different calibers: 7.63mm MAUSER, 30 MAUSER (identical to the 7.63mm, but the English designation of the round), 9mm PARABELLUM and 9mm BERGMANN. This is an example of the 30 MAUSER. Not all versions have the BSA stacked rifles symbol.

 

BSA Magazine - 30 MAUSER

http://www.sturmgewehr.com/dalbert/MGBoards/Mags/BSA%20Magazine%20-%2030%20MAUSER_Web.JPG

 

United Defense Supply Corporation

 

These magazines were not made for the Thompson, but rather for the United Defense Model 42 submachine gun. However, these mags were made by The Seymour Products Company, one of the main manufacturers of the Thompson magazines. They also can be used in a Thompson that has been modified to fire 9mm rounds like 9mm Parabellum. Other than their smaller size, they are almost identical to the Thompson XX magazines.

Sorry about the condition of some of the examples above, such as the rusty Bridgeport magazine with the reverse orientation markings. I decided to include it, though, since it's the only one I have available.

 

XX Magazines Featuring Soldered Witness Holes:

 

Do your magazines have solder in the witness holes that run along the side of the magazine? If they do, they were more than likely involved in the British North Africa campaign during WWII. British armorers filled the holes with solder to prevent sand from penetrating into the magazines. Such XX magazines are fairly common. Many magazines can also be found with evidence of previous soldering, but the solder was removed. My recommendation is to leave the solder in place, as it is a part of the magazine's historical past.

 

Here are some examples of solder filled magazines:

XXX Magazine (30 Rounds) Types and Variations:

 

XXX magazines were adopted after tests in late 1941, and were intended to replace the 50-round "L" drum, which was difficult to reload on the fly, and cumbersome to carry. The XXX magazine also became the favored magazine for the wartime Models M1 and M1A1 Thompson. At least 3 different manufacturers produced the XXX magazine during WWII.

XVIII Shot Magazines (18 Rounds)

 

.45 ACP Shotshells were manufactured for use in Thompsons, and Auto-Ordnance marketed them as a more humane method of riot control. Three different shot magazines are known to exist, with one being a prototype, handmade magazine of single piece body construction. The prototype magazine is not marked in any way, and could have been made for either shotshell, or .45 Remington-Thompson cartridge use. (In the Model of 1923 Thompson Submachine Gun)

Thompson Drum Magazines

 

L Drum (50 Rounds) Types and Variations:

 

Thompson "L" drums are a historical study within themselves. Many manufacturers and variations exist, made from the 1920's to the present, with a wide variety, particularly during the WWII era.

New York Address, "U.S. Model of 1928 A1" Marked L-Drum:

 

This drum variation has just recently been documented. It features the following stamping

in between the rivets on the front faceplate:

 

"ALSO FOR U.S. MODEL OF 1928 A1

 

WIND TO 9 CLICKS"

Note that this drum is missing its retention spring.

This drum was probably manufactured or updated with the new stamping, and

refinished by Worcester Press Stamping Company during the 1936-39 time frame.

C Drum (100 Rounds) Types and Variations:

 

"C" Drums were manufactured in 3 generations, the first during the 1920's, which are popularly known as "Colt Era" drums. Such drums are very valuable today, with prices usually in the $5,000 to $7,000 range. Numrich Arms (Auto-Ordnance of West Hurley, NY) marketed a "C" drum during the 1980's that is known for normally inferior quality out of the box. Most Numrich "C" drums must be fine tuned by Merle Bitikofer ("The Drum Doctor") in order to function reliably. Kahr Arms (Auto-Ordnance) currently markets a "C" drum that has demonstrated fairly reliable results out of the box so far with Thompson Submachine Guns.

 

Colt C-Drum:

 

Original Colt production C-Drums were individually serial numbered on both sides, as demonstrated on the example drum below.

Auto-Ordnance (Numrich) C-Drum:

 

These drums were produced by Numrich in 1985 and were the first C-Drums produced in many decades since the Original Colt C-Drums. The Numrich C-Drums are sturdily built, but unfortunately very few of them work properly right out of the box. Spring strength was the primary problem. Other problems existed with the inner rails, which were somewhat improved with later serial numbered drums off the production line. Many of these drums have already had their springs replaced, and innards tuned by Merle Bitkofer and now work beautifully. If you find one of these drums and are interested in purchasing, contact Merle with the serial number, as he keeps records on these drums, and he can probably tell you if it's been overhauled and tuned or not. (Merle's contact info can be found on the FAQ page)

 

Characteristics of these drums are: Serial numbered, (serial numbers less than 1000 have a zero prefix, i.e. 0186), blued rotor, ribs on the faceplate. (Just like WWII drums) They have winding instructions and a Thompson bullet logo on the drum face at the six o' clock position. The stud holding the winding key to the body is solid.

Auto-Ordnance (Kahr) C-Drum:

 

This drum was manufactured by Kahr in 2007. Some Kahr drums are serial numbered on both sides, and it appears that dual numbering was discontinued soon after production began, as with the example below, which is only numbered on one side.
