I just got a 1909 WC Scott and tonight I noticed on the barrels a VERY faint "barber pole" pattern just ahead of the chambers. No pictures because as soon as I wiped the barrels down it was gone. Nitro proof barrels on a Scott of that vintage wouldn't be twist would they?

PS pardon my ignorance this is my first Brit gun
