Gun is 1469n, O2573 on front strap. Now, the fun begins, there is a larger triangular bodied eagle proof on the left barrel just ahead o the receiver and another on the receiver just in front of the serial. It has a distinct head and long inverted curved top U shaped wings w/a feather at the lower end, its talons are holding a circled swastika. I cant find this proof in any reference work I have. I also bought a $400 camera to post pictures of this stuff and I cant figure out how to make it go..........Is there anyway to post a drawing?????????
