We would very much like to hear the realized price.
I do have it on good authority that the sporting weapon is indeed a JSE(Springer) retailed one, and more than likely to fill an order. JSE preferred the wares of A. Francotte & perhaps his ship was overloaded @ the time of the order. In Europe, it is just seen as a JABC. Across the Austro-Hungarian Empire at hamlets like Tisza St. Imre, Hungary or Nikitsch, Austria, it would fetch little but hopefully a Springer aficionado with a penchant for the period will snap it up?
Last, there might, might be some clues on the backside of the sideplates that establish a maker. In the end, it is what it is, a piece from the Golden Era of Gunning, crafted in subset difficult period of survival.
