Nordenfelt 1" (25mm), non-British manufacture

Whilst I was looking for the LoC to post in the previous Nordenfeld text I found this page from the 1885 Catalogue of Deutsche Metallpatronenfabrik Lorenz. This was an extensively used calibre and I’m wondering what other countries and manufacturers produced it.

It’s not a subject I know anything about, nothing unique there, but I’d be interested to find out more.
