Our grandfather left several steins but the one I’m most interested in is a Reinhold Merkelbach with the RM in a Star of David and the numbers 842. I could not find it in the RM catalog online. I appreciate your help.
I have no idea what SCI messenger is. If you are referring to Facebook, then tell us where to find them there, i.e. date, poster name. If you cannot post pictures, then give us more information about the stein, i.e any text, and description of the scenes shown. The star of David is probably the symbol used by brewers with no Jewish connotation.
