Several years ago on this site, there was a posting about what looked to be a fairly high grade 10 gauge Lefever, but the only markings were "Zischang" on the locks, and (as I remember) the full "A. O. Zischang, Syracuse, New York" on the rib. The owner said Zischang worked for Lefever, and speculated that he had been permitted to build a gun for himself out of on hand parts. Zischang is well known among single shot collectors/shooters for his superb rifle work, most often on Sharps Borchardt actions.
Does anyone know if Zischang actually worked for Lefever?
