I can provide a reference: Chamber Music: An International Guide to Works and Their Instrumentation Victor Rangel-Ribeiro and Robert Markel Published 1993, Facts on File ISBN 0-8160-2296-8 This volume is out of print - I found mine in the bargain section of Barnes and Noble. However, used copies seem to be readily available: a search at www.bookfinder.com provides a list of them. One would have to go through the entire volume to complete a search for the instrumentation which you are asking about. I browsed the final pages, focusing on works that include percussion or flute, to come up with the following matches. Note that the instrumentation is presented as a table, where the various instruments are in columns and compositions are rows. There is a single column marked "Flute/Picollo" for compositions from Beethoven and later, so I could not distinguish between those instruments.
