I think the fact that there are no factory records to answer the poster's question definitively is what keeps us so interested in Lefevers in general. That, and the fact that they are wonderful guns. In my opinion, the best American gun ever made.
As an aside, I was fiddling with mine the other day, tightening down the adjustment screw a pinch to get rid of a tiny bit of play, and all I could think was "why on earth has no one else duplicated this cocking hook/adjustment screw design from a mass production standpoint, or even come close to it"? It defies logic in my opinion.
