Armi San Paolo (ASP) is the predecessor of Eurorams; their 'version' of the 1858 Remington New Model Army is actually modeled after an earlier version known as the Remington-Beals Army Model Revolver. The main distinguishing characteristic is that the frame of the later version is cut back at the breech end of the barrel enough so that the threads on the end of the barrel are visible. This lack of relief on the Beals model caused significant interference problems due to fouling buildup; so bad that often the cylinder would lock up after just one round of firing (six shots). The problem continued, although somewhat abated, on the 1858 NMA also, even after the relief was implemented. It wasn't fully solved until the Ruger Old Army came along, with it's bushing on the face of the cylinder.
The ASP/Euroarms Beals also had one feature from the later versions of the pistol: the hammer notches on the back of the cylinder between the nipples. These were not implemented until the third version in the series was designed.
All in all a very nice cap and ball revolver, well made and fun to shoot. Yours appears to be in very good condition.
