Spoon - 750 - ONLY crescent

[ds1969]

I ask for help.
Coffee spoon from Germany. But the stamps are unusual - 750 and only crescent in the square.
And “H.Rose” - I could not find this manufacturer.
I will be grateful for the help.

This is a German coffee spoon from 1874-1886.
On the upper side - the coat of arms of the Dukes of
At the bottom - the inscription: Johann Albrecht Herzog von Mecklenburg.
Who knows: where can be this spoon?
Palace cutlery?
I know that in the Russian guard was something similar: the officers when entering the regiment ordered cutlery with their names. But they wrote not only the name but also the year of admission to the regiment.
I will be grateful for the tips.
