Anyone ever seen one of these?

Digging through a bunch of accumulated stuff in my black ho....er office and stumbled across this. I thought it went with my 7.62 X 25 Tokarev bolt and barrel that has the sheet metal mag adapter. It was one of those things I picked up at Knob creek wandering the barn when I could get away from my tables. On closer inspection it look like a Beretta M38 20 round mag stuffed into a cut off Seymour mag as it retains the Beretta floorplate. Did the Germans or Italians ever do this with captured Thompsons or is this simply an aberration??????. Hoping someone here has an inkling as to value and/or how the hell it came to be.

My guess is that it is a post-war effort by someone who wanted to shoot 9mm Parabellum out of their Thompson. With the proper bolt, barrel, and mags, this has been done. The UD42 mags work well in a 9mm Thompson, but they are expensive and not very common. Since Numrich and Ciener inserted a .22LR conversion inside a standard WWII .45ACP mag body to feed their .22LR guns and conversions, someone may have tried the same thing with a Beretta 38 mag for 9mm.

 

I do not know of any documented effort by Germany or Italy to do this, but you never know for sure with all things Thompson, especially the magazines, as noted in my book.
