Don't know if you bought it or not but a new A-Bolt is just below $600 usually. If it's a low round count in 'like new' condition it would be a fine deal. Depending on the store/seller maybe you could offer a little less since it's an off time of year. I have several A-Bolts & don't quite know the difference between I & II but I can't imagine it is much. Either will take a Timney replacement spring if you desire. That's all I ever felt like doing to my A-Bolts, not that it was essential either.
