I have owned an Argentine, but it came and went some years ago. It was a shooter too.
As far as the age, we were breaking a newbie yesterday at our own range and I let him shoot my 1873 winchester in 38-40 that was made in 1878. That would make it some 132 years old. I don't shoot it much, but it is what it was made for and I respect it with lighter cast loads. It is always a hit and the cool factor is right up there!
There is no greater tribute to our forefathers than a hunt with their guns. Go for it and get us a big one. he feeling is great!
