I have a 16 ga serial number 356012 Flues,, I think 1921, 28in barrels, seems to be F x IM, the stock and forarm seem smooth and don't feel the checkering but still see where it is. The receiver is very clean but has no case colors, looks like nickol silver or I should say clean/silver. Wondering 2 things, is it worth paying to redo? the wood and did this gun ever have case colors.
