Hi the only markings I'm able to see anywhere are on the arm across the brow and bridge is just gold with an etching pattern on it. on the arm there's an emblem maybe it's a trademark it looks like an oblong C I can't see well enough to tell if there's something inside the emblem and then 1/10 12 KG F thank you for the comment
