GKT and John, I bought it at an auction. Which is where I buy most of my guns. I don't need a crossover stock but for the price that I paid for it I couldn't let it get away. I'm not into hammerguns either, probably use it for trading stock. It's chambered for 2 1/2" and it has been rebarreled. The rib says " rebarreled for Boss & Co." I don't think it means it was rebarrled by them but maybe. I'll have to ask them.
