I'm looking for some help identifying some symbols on the barrel flats of my new French game gun. I have a proof book published in 1976 by Wirnsberger, but these symbols aren't in it. What I'm referring to are the pair of birds stamped on the flats of each barrel. In addition, there's S10 stamped on the left barrel flat. I'm curious about that too, however it's the two pair of birds on each barrel flat that has me curious.
I just added this second enlarged image of the pair of birds.
Thanks in advance for any help y'all can give me.
Steve
