Gibson Reflector Knobs 1980's Gold

This is a pair of bonnet style Gibson knobs, probably from the 80's. As you can see from pics, it is missing the reflector inserts (it appears they were removed, probably because someone did not like the look of the silver or gold inserts that said "TONE" or "VOL".).

I think they are older, in part because they luminesce under a black light, so older plastic.  But the paint on backs is fresh and other than a little chipping in the cup where the inserts were removed, they are in good shape.
