I just received some pre-war K frame silver medallion grips from an auction. They were described as N frame but the seller said he couldn't read the serial number. It was difficult but I managed to read it as 2654XX. However, that would put them in either 1917 or 1919 when the medallion would have been gold. I looked for glowe's posts on late 1920's grips with silver medallions but couldn't pull it up in search. Is it possible the gun they were on was in inventory that long before shipping? Or maybe more likely, the gun was sent to S&W for work and they replaced the original grips with new ones? Can someone confirm if S&W Service Department stamped replacement grips at that time or any other explanation?
