I never found any references to Hollenbeck and Dan LeFever connections during my Syracuse Arms research; and I don't recall that Jack Maedel did either. That said, I don't see how these two guys could have worked in the same town; and in the same trade, and not have crossed paths many times. I certainly want to believe that these guys did meet, and did discuss the gun trade; if under no other circumstances, meetings at trade shows and expositions.
