A "DEFROST" Switch Knob that I got at an auction of vintage car parts.

I don't know if this is OEM or aftermarket but it is, or is equivalent to, Studebaker part no. 526164 and is for use on 1950 Studebaker Commander cars.

I don't think that this was ever used.  The stem and prong that go into the switch have no marks on them.  There are some small scratches in the chrome but this part was packed unprotected in a box with other parts when I got it.  The white paint in the lettering is faded.

The dark areas on the chrome in the photos are reflections from my camera, not damage.
