Can any of you guys with knowledge on the subject tell me what one might be worth?

Good working order, Stainless Steel, 6" barrel.... the only one I found on Gunbroker, which was in comparable condition, was listed at a buy it now price of around $750.
But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil.
