An amazing discovery ! This Merwin has been in a single family for several generations, and treated with great care. It is a 3rd Model, Pocket Army revolver. What is a 3rd Model ? It has the top strap above cylinder, and the straight cut cylinder flutes, unlike the early “scoop” cut flutes. The singular factor making it a 3rd Model it is a Double Action revolver ! By the very late 1870’s to early 1880’s all major manufacturers wee introducing double action firing systems. Colt introduced the 1877 Lightning and 1878 Large Frame Models, and S&W the large frame Model of 1881 Double Action in .44 Russian. Merwin, Hulbert & Co. maintained the SAME physical design of the Pocket Army, BUT reworked mechanical actions to make it a double action firing system. This is an EXCEPTIONAL revolver. Serial No. 2276X, with matching Assembly No’s of 4939 remains in 99.999999% factory new condition. Upon examination, I believe it has never been fired !!! ALL factory applied markings are crisp and visible: side manufacturing address of H&A, frame markings of Merwin, Hulbert & Co, plus Pocket Army. The ORIGINAL factory nickel finish is BRIGHT and 100% present ! ALL the case color hardening on trigger and trigger guard are present. The working action is 100% correct on every feature. In fact so new it has so much suction it is difficult to easily slide open once twisted. It’s that new, but it works 100% correctly. The checkered hard rubber grips are perfect in age color, and crispness, NO damage. It is simply REMARKABLE that this Pocket Army has remained as new for 141 years !!!! The issue of caliber needs to be addressed here as it is such a rare offering. Merwin introduced their revolvers with a company caliber of 44MH, however they quickly realized a loss of market share and re-chambered to 44/40 ( 44 Winchester Center Fire) HOWEVER, they made a quick thought, and made about 100 revolvers in 44 Russian. Why, well they wanted a piece of the S&W business, quickly re-thought the issue and went with 44/40 looking for the Rifle combination pistol cartridge. This Double Action is another example of re-thinking markets, the Model of 1881 S&W revolver was in 44 Russian. Once again, quickly dropped for the same reason as before. HOWEVER a Double Action Pocket Army in 44 Russian is EXTREMELY RARE, maybe only a few, very few. Mow think of that in terms of a factory new condition one, compute the odds !!! As I said earlier, the actions of single action operation and double action function perfectly. The unique open twist and pull shell extraction system works as new and perfectly. I cannot over emphasize the condition of this Merwin. If you are a collector of Merwin, Hulbert revolvers, or Western Frontier revolvers, you cannot do better !
