Thompson Parts ID Help

[Sako]

I have a box of Thompson parts and have had a bunch of trouble with the ID on, who made them, and what they are worth. Hate to sell off my dads old parts but its tough times and I'm not to opening the safe just yet! Knowing him he had them from before there where repros, so I have no idea. One barrel is clearly demilled and the other looks new unused along with a comp.

 

Any help would be huge, other then shooting them I just don't know enough about them to even pretend to have an idea.

 

Thanks!

You have a mix of possible 1921 Colt Era parts, WWII parts, and West Hurley parts. You will need to post more photos of some of the items for identification.

For cost estimates recommend you start with looking at posted commercial sites to see what they are asking for them (Links below). Also, I would not rule out "repros" since the front vertical grip has been copied for many years. Same with the Colt Era buffer assemblys. Not saying they aren't original, but you will need to post more photos of them. A quick id link will be attached as well.

Wood:

The rear stock looks complete and is the later WWII style with the reinforcing cross bolt.

The Front Vertical Grip may be Savage or a repro. look in the channel for a makers mark. Post a photo of the channel and from the front to show the contour.

The rear grip looks like an early Savage. Look at the top to see if there is an S or M marking. Need photo of that as well.

Bolt:

WWII stripped bolt, blued. look for an S, A.O.C. , or R The bolt is complete the firing pin, spring, hammer, hammer pin, and extractor are all in the mix.

Spring guide for 1928. Nickeled steel. Looks like WWII but may be a COLT era. Look for an S or AOC mark.

Colt ERA (or repro) 1921 Buffer Assembly complete, and Buffer assembly rear, incomplete

1921 Buffer Spring

1921 COLT Actuator with a missing Ear (need photo of the good ear knurling pattern)

Paperweight barrel torch cut.

West Hurley barrel with Cutts compensator (compensator does not appear to have the hole for cross pin) ( need side views of the Cutts Compensator)

1 x Brass blish lock Need close up photos. look for AOC or S on side = WWII era. No side markings, COLT Era (post photos)

WWII era or later mag catch with spring on the table

2 x 1928 round disc buffers

Rear Grip screw

Horizonal grip screw

Vertical Grip screw

WWII ring front sight. (what is the marking of the front of the sight) AOC?

Sako,

Thank you for posting additional pictures. You have a few individual parts that may generate some interest. However, most appear to be AOC West Hurley or WWII GI parts.

 

The part I want to discuss with the RKIs on this forum is the 1921 buffer pilot pictured below:

 

 

I believe the pilot is a reproduction. I am not sure about the buffer (tube). Perhaps someone on this forum knows if the buffer was also reproduced in the past. I have never seen an original Colt's pilot with a flat or squared off end that protrudes out the rear of a Thompson receiver. All comments will be appreciated. Let's learn something with these parts.

TD I concur, and that is what prompted my, "I would not rule out repros..." . I purchased a repro from David Lansky who was liquidating a previous forum member's collection (Warren Kraiser) if I remember correctly) after he passed. Maybe he knows who made it. There was a good thread which mentioned Glen Whittenburger, and Stan Andrewski.

Looks like Stan Marked his with an A.

Sandman1957,

I forgot about the Andrewski reproductions and this past thread. +1

Thanks!

And I thought I was the only one who was losing his mind!
