I've collected a fair number of albums over the years in the optimistic hope that art recordings might somehow be usable for dancing. Often, that doesn't work out terribly well. But after teaching a Regency waltz class last weekend and deciding that I absolutely had to have new waltz pieces for this era, I dug up one of my really old CDs, Mozart: German Dances by Capella Istropolitana under the conducting of Johannes Wildner. This is a 1990 CD from Naxos that features no fewer than twenty-five Mozart "danses allemandes" dated from 1789 and 1791, all between one and four minutes long. I can't say whether they were specifically intended for waltzes rather than for ländlers or other 3/4 time dances, but they certainly make dandy waltzes.
