Herschel,
Was the 1924 IM hook butt made of aluminum? There is a threaded hole in the front of the TG for a palm rest but not like the Springfield type palm rest. This hole was a modification after they filled the space between the floor plate and the front screw. I think I sent Michael a photo of the modification. By the way, the TG is from an '03 and not from the M1922.
