Hey guys, a customer came at me with a question, he has an early 70's beautifully kept model 1200 16 gauge with a 2 shot tube. he wants to know if the tube can be modified to carry more shells. He lives on another island so I cannot physically take the gun apart, he sent me some photos and I have done some looking but cannot find out definitively if the spring is being held in by dimple that can be ground out and a different spring but into the tube (we have a tonne lying around), or if there is a stop welded in place. any help would be appreciated.
