Jewelry Manufacturer with Initials W.J.H.? Gold Ring

by Christine
(Louisiana)

I have an antique gold ring with the following marks:

stamped W.J.H. 96 crown 18 leopard head R.
I believe it means 18k gold, British made, London assay office, and that the R is the year. The R. is a block-style letter, stamped into a hexagon. Can you help me?
