While looking for opera buffa files for Baldassare Galuppi, who was as important to that genre in the 18th century as was Offenbach to the operetta in the 19th, I happened on these six menuets, which were included in a 240-page manuscript collection of music for Maria Venier, a resident of Venice. Presumed to be from about 1750, obviously pedagogical in purpose and for the use of a keyboard player, it includes a couple sonatas and sonatinas, a few other pieces, some notation instruction, and many empty pages.
The point of interest here is that the first strain in all six of the menuets is a galant theme, most with a motivically fragmented continuation. I haven't bothered to annotate the scores because the design is identical in all cases.
I found the file on IMSLP, but its original digital source is the Internet Culturale.
