I do not own one but lost out on an auction for one on GunBroker. It had a Lefever ball instead of a hinge pin. I think Mike99 won that auction but that is just a memory or guess. It was a very low grade gun. One of Lefever's sons went up to Toledo after they closed and I expect he had a few rough casting to work with. That was the only one I have ever seen and it was over a decade ago.
