I've been looking over a friend's guns and we found an oddball 25-35 Model 1894 with a half octagon barrel. Serials say it was built in 1898. It has basically no finish left on it but mechanically seems to function well, albeit a little stiff. Any inputs on teardown? Some of the screws are boogered and don't want to budge. Also, any approximate value? Here a few pics....
