I didn't look close enough at what you had typed or the other rib which has: M. Kir. Udvari or Magyar Kirlyi Udvari

Or Supplier to someone court.
I think this to be the German version -
kniglich ung. hof bchsenmacher & Waffenfabrikant


Kirner's royal court dubbing by Prince Rudolf may have been in 1871.
