I'd say it is real. Heinrich peddled some odd stuff and I think there are some collectors/a following today. Heinrich Utendoerffer founded a business or started with a facility in Nuremberg in 1856. By 1890 one sometimes sees Westphalische Sprengstoff Actien-Gesellschaft previously as H. Utendoerffer, sometimes on a patent.
I don't know what it is just yet, but it looks to be some variant of a 14mmX70mm Hochwild and a big brother to a 11.2X51R; therefore, it is probably an odd Austrian cartridge.
Kind Regards,
