I have been sorting and cleaning and bagging and researching and photographing for 2 days with this lot of 324 knobs I got.
I have Identified most of them or i think I have but there are a bunch I cant locate.
Pic 4 in the first post are mod. 20 philco, they are also used as the off/on switch for earlier philcos like 95, 65 and other early large chassis sets.
I tell you that....young Sandra Bullock, the thing they did using those helmets without fluid transfer which Sly did not like.....I'd go for that any time. Seashells be d**ned.
Have had some success cleaning the mildew from knobs with a toothbrush and mild detergent. If on sets that are not used much, paste wax and a little buffing improves appearance. Regardless, if in a humid environment, it'll grow back sooner or later. Most bakelite and other thermoset materials are only shiny on the surface. Abrade this and it'll not shine again. Yup, you can always use paint or laquer with/without bondo on "basket cases" Pays to clean out the center hole, and if fittted with a spring, remove and clear of rust and crud, then put the spring back. Same with set screws. Best!
