I am selling this for an estate of my late father-in-law. We found this while cleaning out his closet and I don\'t know much about it. From what I found on the internet it is a Cast Iron -- Victory single shot Derringer by Stevens model V4.1 with Double Barrels? This was manufactured in the USA in 1880. I am no expert in grading antique toys but this appears to be in excellent condition. It functions as it should, bother triggers cock back and fire when pressed, has no chips, cracks, breaks, or repairs that I can see. Shipping will include tracking and insurance.
