1917 Erfurt

[JCP]

I got this 1917 Erfurt a few weeks ago. It has been buffed and reblued so I know it is a shooter. I have not checked the firing pin or the hold open but the rest of the gun is matching. It has plastic ivory grips and a Mec-Gar magazine, both obviously not matching. The gun is #3761 with what looks to be an " I " without it's dot. It has had the unit markings buffed off the frontstrap with the only thing readable a faint "1". It has the crown/b, the crown/RC and the "flaming bomb" in several places. I understand that the crown/RC are repair/refinish stamps. What is the meaning of the "flaming bomb"? In the left side picture of the breech block ( picture #7 ) there are several stamps, one over the next. What is the meaning of all these stamps? The right side has the crown/B and the crown/RC. The gun has British import marks under the barrel. The gun shoots well and has not malfunctioned since I got the Mec-Gar mags. Any input or comments are welcome. I can post other pictures if anyone would like to see more. Joe
