Wurflein Peanut Derringer. .40 Caliber, 1¼” barrel with a very good lightly oxidized bore. The cast steel barrel is a pleasing plum brown and a light pewter patina shows a nice mottled original finish with some sparse smatterings of light oxidation and perhaps a few very light pinprick pits. The top of the barrel is appropriately maker marked atop the breech with wavy “Sunburst” style marking on the left diagonal flat with dual inlaid silver bands. The tang and the lockplate are lightly engraved and are mottled case-hardened pewter patina with “A. Wurfflein/Phila” lockplate marking; the hammer has turned to a soft brown.
