Yes, the New Service was chambered in .44-40. The New Service was chambered in .22LR (one only), .357 Magnum, .38 Special, .38-40, .44-40, .44 Russian, .44 Special, .450 Eley, .455 Eley, .476 Eley, .45 ACP, .45 Colt. (Did I miss any?)
Such a severely modified revolver has almost no value to me, but to some, it may be worth a few hundred as a "shooter." I would rather save my "few hundred" and put it with a "few more hundred" and buy a well-worn ORIGINAL "shooter." A severely modified "shooter" will always be a dog. Unless you want to run a "dog shelter," I would avoid it.
