Well for those who love these scopes as I always have here ya go! Trying to find info on these old, but awesome scopes, is next to impossible. I'm doing just about complete heart surgery on mine minus the cross hairs, as they are in good shape.. Not many people have seen the insides of one and I thought of all you guys.. Yes laugh I need help posting pics.. But if some one could give me some help every one can see this?!? If you have any questions I'll answer what I can?
