Another 3 Prong Fork

[moonshine]

Hello All. The marks on this one are very far gone, but any info. is appreciated. I'm not sure it is french at all.
It has the same crest as the other Fork I just posted, but I'm not sure it's the same maker. 7 5/8, 66 grams.
Than you in advance.

Very worn, but perhaps London 1763.

Thank you.

Definitely London but I think a bit earlier 1753?. Could you post a close up image of the mark nearest to the fork prongs, which looks like it may be the makers mark.
