Like yourself, Mark, I greatly admire the LeFever aesthetic. Beyond that, a lot of the technical aspects seem to be gimmickry that shouldn't really be needed in a well built gun.
I know what Lefever was trying to do, but I'm just saying. That ball joint sure is fun to play with, but if lubed hinge pins work just fine, why design something for the person that won't help maintain his own gun? Maybe the adjustable bolting was required because the system seems kind of skimpy in the first place. And so forth.
Don't get me wrong. If I had one in nearly new condition, I think I could make it last forever (i.e., my remaining shooting years) and I'd love it to death. But a good Smith would last longer.
