Does anyone know what these are for?

I have three or four of these that are NOS.
I don't see any identification on them.
Thanks Lee

Try taking a picture with a white background (like a stock photo) and then use Google Image Search to find similar images. Might come up with something useful.
Google image search: images.google.com

I can't tell how big they are but they look like hydrodrives for a low-end hydrostatic driven mower. I had a Peerless drive in my old mower. I never removed it but it looked very much like those.

Sort of like looking at ink blots.
