I have a nice, rarely used 32 inch BT99 serial #01233MW177 with three chokes M/IM/F (maybe 50-75 lifetime rounds total)? If you’re still interested? Original owner - bought it for wife, she never enjoyed the game. i have a nice Browning case, and the original box.
I have a 1979 BT99 that is a 2 bbl set IM and Full, no adjustable comb but it doesnt need it, it pulls up nice. I have added an adjustable butt plate to it. Also comes with a older original Browning 2 bbl case with it. the IM bbl is ported the Full bbl is not. PM me if you are interested.
