RedofTx:

The "13" is a plug gauge stamp noting the passing of 0.700" or 0.710" diameter plug the whole length as does the "41" which notes 0.484" which is pre-rifling diameter. The other marks, was their an imperial eagle, any crowns, crown over anything(V, BP)? Was the bore gauge stamp between any marks? Sounds a little British??

Kind Regards,
