This one appears to me to be a Lexington, it has pretty distinctive lugs. Movement is marked "47", case S/N starts with a "6", with no additional date code stamping. Engraved as a gift in 1947. As received and it looks like it spent most of it's life being admired in a dresser box, worn only for special occasions.
Do we ID this one to the potential case date of 1946, or movement date of 1947? I'm fine with either based on Panel consensus.
