Post-bellum maybe; because the DJV-Ausschuss for cartridges had, in its infamous recommendation / decree of 1956 (actually, a late effect of Albert Preuß' writing from 1900), classified the vom Hofe cartridges in the second category of "Spezialpatronen" '(first category were "Standardpatronen", third category were "auslaufende Patronen"), and e.g. DWM immediately bowed, cowered deep down with wiggling tail, and arranged its catalogues henceforth thus. Eventually, the distinction got lost however.

Ante-bellum however, I think that Christoph Funk frequently sold rifles and combination guns in the then existing vom Hofe calibers.
