Unsure of the exact gun this goes to but an expert like you might know. This is a item that needs to be restored but it's integrity is 100%. Please look at photos and ask any questions about the item and I'll return it promptly thank you.The Antique vintage single shot derringer-style cap gun or toy pistol hammer piece, dating back to the year 1900. This vintage gun carries the colored makers by law to indicate it is a toy gun. But this is just a hammer to a toy gun so it is not a toy gun but I have to put this disclaimer.
