1920 Police unit mark

[Herb]

Don, I got it today, here is the other info you wanted, there is a suffix, 'a' the sear safety has been removed, just a hole in the frame now while the spring thing is still on top of the side plate which has been cut out and there is a slot cut into the frame side just above the left grip, nothing in there either. It has phony 'black widow' grips on it and the refinishing looks like black parkerizing, no buffing is apparent as everything is sharp and crisp, it looks like it was bead blasted lightly before being refinished. Might be an ex Russian or VOPO, as there is an X following the serial # on the left reciever. Bore is excellent, the best I have seen actually. The small parts that are usually strawed are black except for the ejector which still retains a little straw color. The unit stamping is really low on the grip strap, starting just above where the grip strap starts to curve to the magazine well . It has an importers stamp on the bottom of the barrel, GAI MIA FL. The magazine that came with it is a Mecgar replacement mag. The locking lever is numbered 82 and is the only non matching part. The right reciever still has the original triple AYA4 eagles of the 1920 DWM police models. I'm curious about it being parkerized rather than blued, any thoughts on that?
