Whats this crankset from?

I posted a pic of this before, but I'm not sure what this came off of.
It was in a lot of parts I picked up a few years ago.

Was this Schwinn or just a generic sprocket design?
I need to know what it fits before I trade it away for something I can use. (I need to make sure its not something that fits a bike I've got here).

Not sure but it is cool.
