The closest I have is a B&L mount and scope for a Savage 45. I could send you some pictures if you think it would help. On the 40/45, the B&L mount looks like a Redfield Jr. from a distance but it is a two piece affair that consist of a base screwed to the receiver and another piece that holds the rings and slides within a dovetail on the base. I did not expect to see a 99 like yours with a crescent butt plate and the latter barrel with the raised front ramp. It looks like you scored a nice TD there.
