Thanks, Kutter, for the full story. The "sporter" 1941 I handled was obviously a parts gun made up by Winfield, and now that you mention it, those were Winfield Arms ads I was seeing as a kid. (Only thing I ever actually got from them was a $9.95 mail order BSA Cadet action--now a .25-20).

Never saw one of the detachable mag REAL sporters; must be pretty scarce. There isn't even one (prototype military or sporter) at the small arms collection at Aberdeen Arsenal, if I remember correctly.

Weren't all the govt. contract "Johnson Automatics" barrels for the '03A3? I seem to remember seeing one on an '03A3.....or were they also for the rebuilt 1917s we handed out to our Greek, French, and Chinese allies in and after WWII?
