i have this Lefever arms 12ga single shotgun .
and it has B P and 12 , and patent applied for .stamped on the bottom of the barrel, the end that goes in the receiver and # 13058.
on the top of barrel it has ... long range feild and trap stamped on it.
on both sides of receiver it has ... lefever arms co. Ithaca ny and a flying goose.
i was wondering what the B P means, does it mean black powder or is it just a proof stamp?......thanks ......hubb
