Need help identifying silversmith on 18th French silverware

[fermiersgeneraux]

Hello All, here's a pair of silverware (matching fourk and spoon) from the 18th century, in the style of filets, double seashell, and hallmarked for Paris, 1766, but I am having trouble figuring out who the silvermith might be....
Four hallmarks visible on both silverware:
1. Charge mark for Paris, 1762-1768 (crowned A with laurel)
2. Discharge mark for Paris, 1762-1768 (dog head - tete de braque)
3. Letter date mark for Paris, 1766 (crowned C)
4. Silversmith mark - initials "TBB"?, and a star (see photos)

Initially, I thought it was Jean-Baptiste Bertin ("JBB", a star - became silversmith in 1740, died 1770/1771), but the photos look more like the initials "TBB"..any help or insight would be appreciated, thank you in advance, fermiersgeneraux

Hello
The charge, discharge and date letter marks are not legible on my monitor.

However, the maker appears to be Thomas-Bonnaventure Barat. Barat was apprenticed on 29 October 1746 to Jean Thibaron, received as a master on 21 January 1766, and registered his mark on 26 January of that year (TBB, a star), residing rue St. Bon in Paris. He was listed as retired on 10 December 1781. See Nocq, v. I, p. 64.

If the maker is correct, then this is a very early example of Barat's work according to the other marks.

Hope this helps.

Thank you very much, JayT - your insight and information is always on point.

I'm reasonably sure of the dating of the hallmarks, but of course, as it goes with these things, I could be wrong. I'm listing below additional close-ups of the other hallmarks for everyone's consideration and input.
