Hey guys, my friend has a Remington Rand no. 50072xx. This too high for the serial charts, it also does not have the US property markings, but does have inspectors mark(FJA) and proof P's. I have not seen it so I haven't been able to inspect it in person. Anybody ever see this before, could it be as easy as a RR slide on a different frame? Any help would be appeciated, thanks
