Still playing with my new toy (1898). Just received today the stacking swivel that was missing and an oiler and 3pc cleaning rods all thanks to Mr. DeChristopher. He is such a nice guy. I noticed a W behind the trigger guard and was wondering what that stands for or is it some kind of inspection stamp. Only other stamps on the stock are the 1899 cartouche and the P in script behind the W. Also I assume the correct way of loading the trap door in the butt is to put the oiler in first, knurled cap first and then the cleaning rods. Please advise as I am learning quickly on this site!
