Thompson magazine converted to 22 cal rim fire

[RCS]

I found this some years ago and was impressed by the work involved to convert this 45 ACP magazine to work with the 22 rim fore cartridge. I am certain this magazine came from Numrich as they offered a "drop-in" kit to convert the Thompson Model 1928 to fire the 22 rim fire cartridge during the 1980's ? This kit had a special barrel liner and lightweight bolt, magazine or 22 rim rifle drum.

A special stamped magazine retainer was made to hold the Reising 22 rim fire pistol magazine which was held in the magazine by the spring, very solid arrangement. I can
only assume that this magazine conversion worked, as to the "drop-in bolt and barrel liner, I do not have any information
