John the drawings that I posted are for Featherweight guns. On the top of the page for Part No. one is 67a-FW and the bottom is 67-FW. What the "a" means I don't know, but one is longer and so is the one in your nephew's drawing. For the Regular frame guns Part No. would be 67-R. It shows their largest diameter at .308 compared to the FW at .274-277. Basically, the other dimensions are the same except that the length of one is shorter at .907 compared to .928.
