Unknown Knife & Fork

This is a very rare matching knife and fork set most likely made in Germany in the early 19th century or maybe late 18th century. The set has handles made of hard paste porcelain and is decorated with a ncie relief design which is hard to show properly in pictures. The metal parts are steel and the ferrule is made of brass or bronze. The metal goes all the way through the handle and a little piece comes out the other end which was flattened to hold the handle in place. The metal parts seem to be original rather than a later replacement but I am not sure. The knife is in great condition with oxidation to the metal parts which is normal and the metal point coming out of the end of the handle is missing. The fork is in OK condition with a crack around one side of the handle (coming down one side - going over and coming up the other side). It never came off but could do so at any point. The metal parts of the fork are rusty as well. The set is unmarked which is always the case. The fork is 6.75 inches long of which the handle is about 2.875 inches. The knife is 7.75 inches long of which the handle is about 2.875 inches. Please email me for more information or other pictures.
