I just bought one of these rifles at a gun show. 12/2004. I paid $130 for it. It appears to be in working condition. I have not tested it though. Bore is a little weak, but still in usable condition. I haven't seen a price guide on these rifles, and have no idea of the actual value, But after a considerable amount of horse trading I got one for $130. So I guess that can be a starting point in determung the value. I was told that the Hopkins & Allen model 722 is possibly the same gun. They sure look the same to me as well. .
Virtually impossible to determine caliber by just the serial number.
Seldom reach or exceed 100
Seldom exceed 100 USD
Caliber can not be determined by serial number.
No way to know the caliber from just the serial number
Serial numbers do not designate calibers. Look on the brrel to ID the caliber.
Can't tell the caliber from just the serial number.
It would be in 36 caliber or 44 caliber...
By model, caliber and serial number.
the caliber is stamped on the gun.
