Hi, guys,
Sorry, I don't have any pics of those conversions as I never bought one or wanted one. Frankly, they were hacked up junk except for the ones made by Beretta and a very few other places. Many of the ones converted to 7.62 with M14 mags were cut-and-weld receivers made from scrapped receivers that had been cut in two and then bought by various companies and welded together.
The conversion is not easy, as I said, and I have seen probably a half dozen M1 receivers ruined by folks trying to do those conversions without really knowing what they were doing. It is not as easy as just putting on a new barrel and an M14 trigger housing.
BTW, Unclenick, the main army problem with a detachable magazine at that time (1930's) was the feeling that it would make the rifle too awkward and would require a big hole in the bottom of the rifle that would gather dirt. As it turned out, the M1 clip saved millions of cubic feet of cargo space that would have been required to ship the magazines; that may well have more than balanced the tendency you mention to fire off or eject rounds so a full clip could be loaded.
