I bought recently a 1948 Jos. Winkler 16Ga shotgun. It is in very good condition. Anson & Deely scaloped boxlock, Greener cross bolt, plain wood. Their 70 cm barrels do not show their make aside from an (M) and another indescribable marking. Does anyone knows how many steel makers could have supplied barrel blanks, Bohler included, to the Ferlach gunmakers right after WWII?
