This is certainly a replica, made by Willem van der Eng a Dutch Collector. He has made a number of replicas, mostly of very rare experimental German cartridges.
The headstamp was a capital R in circle or the word copy on 12hrs and on 6nhrs ern or er.
The meaning of ern: Eng Reuver Nederland and er: Eng Reuver.

Regards,
DerkJan
