Masterpiece:
Here is a photo of the SN on the butt of my new NM#3. I have altered the last two digits of the SN, but you get the idea. There is clearly something marked to the left of the lanyard ring boss, or whatever it's called. When Don looked at it he thought it was the remnants of the original SN that had been polished away before the current SN was marked. I could not see well enough to make it out. However looking at this photo, the marking almost looks like a proof mark of some type to me. My brain is trying to make it look like a winged eagle with a sideways letter A over the top.
What do you think?
Just for the heck of it, here is the legend on top of the barrel rib. No blue left in this area.
There is also a small trademark on the right side of the frame. Other than the SNs on the rear of the cylinder, and the latch, this is all the markings on the outside of the gun.
