Vintage butterscotch swirl steering wheel spinner, measures about 1 3/4" diameter.
It may or may not be bakelite but it certainly has the look.
Cast base is missing most of it's old brown paint and has a small chip where it mounts.
Knob has a chip at the base where it mounts to the base.
Clamp shows some rust but screw & threads are all good.
I see no maker's mark.
This would mount to a steering wheel of 1 3/8" or smaller.
Please ask any questions before buying.
This will be shipped no later than the weekend after payment is received, usually within a day or two.
