flatware

i was hoping to gain an evaluation and also information about fernando esser (remsceid) as an   silversmith maker... I have a set of sterling or coin silver flatware marked  fernando esser .I  would like to know if this is rare/ it appears  to me  really rare because I have found nothing on that topic. I have found tons of information about swords and knives he produced in  1799  until his death in the 1800s . With that said  nothing at all about flatware he made neither with his name ,althorough it seems like a chat room had stated that often flatware was sometimes exported without being sent to the assays office,especially by german silversmiths.Finally I want to know whether for so much ,when did esser begin making flatware,and with whom.I am also curious about the value of a set made by him .I have a large set and thought it difficult to to take a  picture of 130 pieces . 

Good
