Don, I will look tonight (if I remember) at what I have laying out (had an ATF inspection scheduled tomorrow, but it was cancelled). I have owned several of these, and seen several more.
I think what throws many folks off and myself included is that the receiver cut and imperial markings / date is not a guarantee that it was an artillery.
So, I have a tendacy to overlook these, I simply do not have the inclination of some collectors of looking really, really close at my lugers, a mental failure on my part I know.
