I have a 1861 Navy that was made by ASM and sold under the CVA label. It's probably one of the nicest looking revolvers I've had over the years - great fit and finish, beautiful wood - very impressive.
My only concern is with the internals as Doc points out I've heard they are on the soft side but so far, mine has had no problems in regards to that. If I do have a problem, it may be hard to find any parts and they'll have to be fitted from other makes I guess.
Irregardless of that . . . you got a nice looking Army. Shoot it, enjoy it the heck out of it and don't fret too much about "what might happen" . . . just enjoy it. It will last you a long time.
If worse comes to worse and you do have problems . . part it out and sell 'em on flea bay. I've done that with several "parts revolvers" and it just blows my mind on what folks pay for parts. The parts brought much much more than I had into the revolvers to begin with. Then you take that money and put it towards another Army (if that's what you like) and keep on shooting!
Congrats on your find and enjoy! It should be a good shooting handgun and will put a big smile on your face! Enjoy!
