Hello,

The Wikipedia article of Chopin's Waltzes:-
http://en.wikipedia.org/wiki/Waltzes_(Chopin)

Contains a list of all Chopin's composed Waltzes (All his Published ones as well as the lost ones). If you scroll down there is allegedly an A minor Waltz composed in 1829 (?) which involved a brief prelude and sketched main theme, however; it doesn't state it as lost. Has anybody here heard of this? I know Wikipedia can be very unreliable, but I was just curious considering the rest of the information seems pretty decent.

Regards
