Nice catch Toyman. I'd love to find one with those add on features.
I have a few pre war OM revolvers and was wondering about your serial number reference. I just picked up a OM in 22 with a four digit number that shows 1930.
I was looking at Proofhouse (Serial Number Data) under Officers
Model and the 1932 range is 6700. The 1950 range is 57200-57320 and the chart doesn't get to a six digit. Is my reference material is wrong?
