The cheekpiece has decorative carving at the front and rear. The stock has several scattered light to moderate compressions, drag lines, and bruises, mostly under the finish. The wrist has cracked through at the rear of the lockplates and been repaired. The stock has cracked through forward of the trigger guard and been repaired.

Overall Condition: This shotgun retains about 0% of its metal finish. The barrel displays its intricate damascus pattern and has mottled patina throughout. The plates, hammers and tangs were possibly finished in the white or they have worn to white with light, scattered patina. There are a few scattered light marks and scratches. The front nipples are in good shape. The left-rear nipple has a chip loss. The right-rear nipple has a crack almost all the way down its side. The screw heads range from sharp to lightly tool marked with strong slots. The engraving is clear and crisp. Overall, this shotgun is in about Fair-Good condition as Antique.

Mechanics: The right-front hammer does not catch the sear when cocked. This can be problematic as the front trigger fires both right barrels, front hammer first. The stock has slight flex to the receiver and we found that if the stock was gently flexed, it would sometimes trip the mechanism and allow the rear hammer to be dropped from full cock. The rear trigger controls the left hammers, and appears to function correctly. The right rear hammer appears to function correctly once the mechanism allows it to be dropped. We did not fire this shotgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance requirements.

Box, Paperwork & Accessories: This shotgun comes with a brass-tipped ramrod with tamper at one end and threads at the other. The rod shows light wear, in about Very Good-Fine condition.

Our Assessment: This is something you don’t see every day. Superimposed or “stacked” charges are a concept that goes back as far as the 17th century and even made a brief appearance in the 21st century with Metal Storm. With a percussion gun, ideally, the projectile forms a seal on the rear charge, allowing a second charge to be placed in front of it and ignited with a separate cap. This shotgun is a double-barrel with two hammers on each side allowing for four total charges to be loaded and fired individually (you hope). One of the dangers of this system is that if the rear charge is also ignited, dangerously high pressures can be developed and may blow the gun up. The best case, if you have a double-ignition, is just that the gun has significantly more recoil and may be difficult to hold onto. That may be what brought about the cracks in the stock. Either way, this is an innovative and rare gun which will make a fine addition to any antique arms collection. Please see our photos and good luck!
