Very nice. Re your trumpeter- maybe I can add some information.
1- Up until mid-1759, the Trumpeter should be in a red coat, faced and lined with blue, heavily decorated on front, cuffs, sleeves etc with white lace which had a blue stripe running through it. This was the livery of the Bethune-Sully family, who held the colonelcy up until then.
2- After mid-1759, the Trumpeters coats were green faced and lined with yellow, with orange and black lace (or possibly red black blue, orange like the saddle cloths, although in other regiments the trumpeters seem to have had slightly simplified versions of the full livery lace).
The uniform at 2 was previously used by the trumpeters of the Commissaire-General Regt until mid 1759, when M de Castries transferred to the Mestre du Camp as its Colonel.
The information on the Kronoskaf site is slightly confused and back to front in this case.
