antique french ivory celluoid handled table knives, early 1900s vintage Sheffield England

Lot of two different sets of four knives each, antique table knives with yellowed french ivory celluloid handles. These all look rough, a good cleaning and polishing would probably help.

These have such a lovely old design with the wide dull blades. One set has crimped edge on the blades, the other does not. The flat blades are marked Sheffield England. The crimped blades are not marked at all that I could see.
