Saddlemount and an older model Aimpoint red dot, extended choke. Gun is long gone. I swapped it even with a man four years ago for my 1939 Ithaca NID Magnum 10 3.5" 32" barrels that I had sold to him decades ago. I bought the gun out of Shotgun News ad from the late Thad Scott of Indianola, MS. sometime in 1978-80.
