Manufactured from 1863 to 1867. Two line New Haven address marked on top of the barrel that is manufactured without a front sight. Spur trigger, checkered hammer, and smooth bird head grips. Barrel, frame, and left grip panel serial numbers match.

Fine with the frame retaining approximately 90% of the silver plating and the barrel retaining strong amounts of nickel in the protected areas with minor pitting. The derringer retains most of the barrel marking. The revarnished grips are very good with a few minor dings and some minor scratches.

Manufactured between 1863 and 1870. Silver blade front sight on barrel marked "OK" on the top flat and two line address on the right and "J.P. LOWER" on the left. Spur trigger, checkered hammer, and smooth bird head grips.

Very good as partially refinished with the frame retaining virtually all of the current silver plating. The barrel exhibits a smooth mottled gray patina. The grips are very fine with some minor scratches and a few light dings, chips and dents. The markings are clear. The action is very good.
