Difficult to ID with certainty from viewing just one photo... but it looks like a "double reed" from a musical "wind instrument" (meaning, one you blow into to create musical sounds). If my guess is correct, somebody else here will be able to tell you the specific version of musical wind-instrument it is from. (I'm not an expert on musical instruments.) That being said, here is a photo of a piece of musical instrument with "reeds" that I've dug a specimen of. It is called an "Aeoline" and it dates from approximately the 1820s-30s. But of course, musical-instrument reeds are still being manufactured today... most commonly in harmonicas.
