This is an Eastfield 916A 12 gauge pump shotgun produced by S&W. This particular model was aimed at police agencies and was also used in Viet Nam. This model has a 20 inch barrel with a 3 inch chamber. The magazine holds 8 rounds. It has a tang safety. The shot gun was produced from 1972 to 1978 with not SN dom is not available. This gun has seen some use with a replacement recoil pad and a solidly repaired crack. I would call this a utility shotgun rather than anything collectable. Asking $175,00
