I do not see any markings on the gripsAppears to be in excellent original condition to me. No factory stamps for a refinish. Looks like a very nice one to me. Do the grips (right side panel, maybe in pencil) number to the gun? They probably do but if not they are correct for a Triple Lock from 1910 on.
There might not be any but the pencil ones, being over 100 years old, are often really hard to see. Sometimes tiling them under a bright light will allow the lead from the pencil to shine a little and the numbers can be seen. No big deal really, just another nice to have on a really nice old Triple Lock.I do not see any markings on the grips
