battle,
I can't make out all the marks, but I do see a Crown S for proof with shot. and the Eagle N nitro proof. It seems to have been proofed in March 1941( if I read 341 correctly). It shows the Zella-Mehlis proof house mark( pine tree in a heart), giving Raimey's guess of Venus some credibility. If you sell it, where would it be shipped from?
