I was wondering how common are the 10 gauge guns that have LC Smith maker of the baker gun are?Syracuse NY stub twist is also on the barrels. This gun is in overall good shape. The only crack I could find was on the inside of the ebony tipped forend. The gun did not have the (pins?) where the hammers strike the barrels. Are these still available if I decide to get this gun? The SN is 2649A
