Original and rare, factory manufactured oak case, with six securing screws in the lid, partitioned for a British proofed Colt “Thuer” Third Model derringer. Lined inside with blue beige to base and lid. Triangular compartment, with ivory pull knob on the lid, in the top right corner of the case. It has an open compartment for ammunition and an area at the bottom to accept a L-shaped slotted iron cleaning rod. This oak case, with its vacant circular brass escutcheon on the lid, comes with its original key & tag. The case measures 6 1/2 x 4 x 1 3/4 inches. Overall in fine to excellent condition. It will fit any Colt third Model derringers, but the snuggest fit is the sloping trigger version, with the wide grip.
