After five years of searching

[Eric H]

I finally found the channel knob for my Stewart Warner 9100B mirror in lid set!

I've been searching eBay every day for about five years looking for this knob, all I had to go on was a picture someone sent me, I had about given up hope of ever finding one.

I actually missed it the first time around on eBay because there were four pictures on the Auction and I thought they were just different angles of the same knobs, turned out it was four different piles of knobs and this one was in the second pile!
Luckily it didn't sell and got relisted with a $10 BIN for the whole lot.
