Hugh,
If its just frames, the serial number will do, and if its marked GERMANY. If the safety lever is present and it is a type-2 (or a type-1!) thats good to know. Also if the takedown is numbered on the right. Also if its long frame or short. Hmmm, I guess thats more than just the serial number, isn't it?
If it is just a P-08 frame, I'm interested in the number if it is 5-digit.
Thanks much, and looking forward to the c/RC info.
