This is the WH M1 TSMG that has just returned from PK. I bought it new and unfired in its original box, but could not get it to fire more than a few rounds without jamming or failing to feed. I asked PK to emulate a wartime M1 as closely as possible since the gun is marked as an M1. He replaced the cast WH internals with GI parts and completed the machining operations originally omitted. He recontoured the receiver and frame to GI specs and pinned the front sight. The milled grip mount is a beautiful item of his own manufacture, as are the rear sight rivets. The receiver and frame are matte blued, and the stocks and grip are WWII NOS GI. A nice final touch was the addition of a small Diamond K logo where the ordnance bomb would be found on the WWII guns. It is impossible to convey with words and pictures the quality of the work that PK bestowed on this project. PK's work is exemplary, and is to the very highest of standards.
