Assistance with maker of Sauce boat

[dartsil]

Hello all ,
I am posting this on behalf of a friend,
Its thought to be 17th century French or 18th century Hanau, my thoughts are that its Hanau but would appreciate if anyone can shed some light as to the maker of this very fine looking piece.

The family whose arms are cast and applied to the sides, Comte de Brandt de Marconne. Here are the details:

Dimensions
Height: 6½ in. (15.51 cm.)
Length: 7½ in. (19.05 cm.)

Weight: 15 Troy oz. 6 dwt. (485.22 g.)

Thanks in advance for any information we receive

18th century French or late 19th early 20th century Hanau
