Early Tablespoon - Help with Hallmarks- 1760s?

[pauline5555]

Have an early spoon from London. Two hallmarks are very rubbed. Looks like one is a crowned leopard head and a date letter I am unable to decipher. I think the maker is William Fearn. Any help would be appreciated. Thanks

Looks to me like William Fearn 1772.
