Serial numbers were not required on shotguns or rifles by the Federal governmant until 1968. Any company that did so before that was marking them voluntarily.

Shotguns neither fire bullets, nor do they use clips. The capacity for each shotgun will vary by model, load, and magazine. A Remington 870 off-the-shelf holds five rounds. The Saiga shotgun uses a detachable box magazine which may hold anywhere from five to 30 shotgun shells.
