[Lancer]

Always a great day when one of us gets a new toy, congrats. Mines a 28ac also, 1509xx. Seems most ac's are in the 150,000 range. I feel your happiness!!

Welcome to the club.

[Merry Ploughboy]

Congratulations!

Send drum to Merle (see FAQs) for going over and greasing.

All WWII vintage 28s (and M1s and M1A1s for that matter) were not originally finished with Parkerizing. Who cares.

Enjoy many happy times with your Thompson!

Can anyone tell me about manufacture date of this S/N range of AC's?

pat k,

Auto-Ordnance opened their own plant in Bridgeport, CT in late 1941 to meet war time demands. The 1928 Model was only produced until late 1942 or early 1943 when all Thompson production was switched to the M1 series models.

That would put your gun as being manufactured sometime in 1942. Virtually all of the guns converted to the AC designation originally had later features such as the smooth barrels and Lyman stamped "L" sights, so it stands to reason your gun was most likely manufactured in late 1942.

The source of this information can be found in various locations in Frank Iannamico's book "American Thunder."

Pat,
I checked "American Thunder" last night. The last 1928a1 manufactured at The Bridgeport factory was made on 15 Oct. 1942. Total 1928a1 production was 323,900 at Bridgeport. This would seem to indicate ac's in the 150,000 range were made in the spring of 1942.
It'll be interesting to see if "American Thunder II" has any more facts on production history.

Somone gave me a copy of a two page summary of factory shipping records, prepared by Frank Innamico in 2000. The summary lists monthly delivery figures for 1940, 1941, 1942, 1943 and 1944 (thru February). The grand total is 1,497.334 of which none were delivered in January 1944 and 4,091 were delivered in February 1944. The summary indicates the Total Thompsons delivered in 1940 as 43,811 and 287,349 in1941 for a cummulative total of 331,160 by the end of 1941. When I looked up my 1928A1 (S/N 165xxx) my best guess was that is was delivered in July 1941.

hawksnest,
Correct me if I'm wrong but the figures you are quoting appear to be Savage prodution numbers, my numbers refer to Bridgeport production which is where all ac's appear to have been made.

I'm confused by all these apples and oranges. Bridgeport is a city, not a manufacturer. ACs are Thompsons equipped with Cutts compensators. Do you mean "AOs", Thompsons made by Auto Ordnance Corporation in Bridgeport, Connecticut? Was the "c" just a typo?

Phil,
Sorry if my post wasn't clear. My earlier post refers to the factory in Bridgeport. Yes, I mean AO production and 1928ac's

[First Sergeant]

Last week I took delivery of a 1928A1(AC) that was, as the AC indicates, taken from the inventory and sold commercially to police departments. Mine has the "US" ground off and the C overstamped on the "1." It has the Lyman L sight and a smooth barrel with a Cutts compensator. The only differance from pat k's is the serial number is a bit lower than mentioned in this post. The serial number is in the 133,XXX range and the upper matches the lower. There are no acceptance marks on the gun at all. It came with a bright bolt and an original oil bottle in the crossbolt stock.

Would this gun also be in the 1942 range for being manufactured? The gun appears to have original parkerizing and has the crossbolt stock (has the PD's numbered metal inventory tag embedded in it). If I recall, the crossbolt stock and parking would occur during the arsenal rewoking but there isn't any arsenal marks either. Any thoughts?

What can you tell me about AO 1527_ _X ?

You are going to have more fun than you imagined.

[john]

My Bridgeport 28 is marked "U.S. 1928 A1". The "US" was not ground off and the "1" was never overstamped with a "C". Serial # is in the (A.O.)51xxx range.

How common is this? Just curious........
