Where does this knob go?
 

I was working on putting my dash together today. In plastic bag along with the other knobs was this one knob.
I can't seem to find where it goes. It isn't one of the A/C pull knobs although similar shape. Not for the choke, or lighter cause it isn't threaded. It definitely isn't for the wipers cause it doesn't have the hex hole at the bottom or one through the center. Any ideas?

It's not for a C10 dash.

Thanks! I'll toss it in the unused knob pile I've collected.

I think that might be an early to mid 60s F100 dash knob

It looks like a Ford knob.

FORD! I'm going to throw it in the junk metal bin. I don't want it contaminating the Chevy knobs.
