My "Thompson" submachine gun

A follow-up to my last post.

Here's a photo of my assembled 1921 upper.

Here's a photo of my 1921 upper disassembled. Those parts circled in red are the ones that were modified in the 1928 conversion.

Here's a photo of what appears to be an original converted 1928 actuator (not mine). Notice the extra steel and rivets. All actuators made later were made in one piece. Only converted Colt actuators are riveted like this.

And here's a diagram of 1928 parts that are substituted in the conversion:

I would attach a photo of mine assembled in 1928 configuration and the 1928 parts, but I don't have time this morning to pull it out, make the switch, and take a photo.

A final comment. I much prefer firing mine in original 1921 configuration than in 1928 configuration. The faster firing rate makes it much smoother and easier to keep on target. The slower 1928 firing rate makes it feel choppy and jerky in comparison. John Thompson got it right in the 1928 configuration. It is an awesome weapon.

One more interesting fact. My M1921, No. 6835, was delivered from Colt to Auto-Ordnance on October 31, 1921 (Happy Halloween!). Auto-Ordnance sold it to the Grosse Point Shores, Michigan police department. Eventually I became its custodian on November 7, 2011 just after its 90th birthday.

There were always some die-hard Nazi troublemakers in the US POW camps, but they were kept segregated from the average Feldgrau grunts who weren't really Nazis.

My father was in a POW camp in Epernay, France. In that camp troublemakers and die hard SS hiding among the regular Wehrmacht prisoners often had to deal with a Garand or a 1911.
 
Many eons ago I was issued a Thompson M1928 which was replaced by a Thompson M1, and then by a M1A1 (Grease Gun). I was a young 135#, 5'8" 18yoa "Coastie" with pimples. Being a "Non Gun" person I liked the M1A1 Grease Gun because of the lighter weight and easier field stripping. After the Grease Gun came a M2 Carbine which was yet lighter !
