My question regards the engraving on the back. It looks like the initials M R, but neither really looks like German handwriting of the time. I've attached a photo, below, and I've also used a red line to indicate how the second initial is shaped. I have not been able to get a really clear picture so this is my solution.
I would like to know if this engraving looks correct for c1820, Hanau, Hesse, Germany, or of it suggests something else.
Thank you.
