vintage sterling silver cheese server & prawn fork w/ mother of pearl shell handles

Lovely old sterling silver cheese server and prawn fork with mother of pearl shell handles. These have some hallmarks which we're having a difficult time making out - please see our photos.

The fork measures 8" long tip of fork to the end of the handle, and the cheese server is about 6 1/4" long. They have nice weighty feel as the old sterling pieces do. Both have some tarnishing, we've left them just as we found them.
