I need to open up some of the later ones & have another look. I think they quit using the carbon types later and just used a wire spool type so it could be adjusted. They must have had an assortment of those carbon types when they were testing out those units at King Seeley. I've seen different color codes on different units so they likely just installed ones that best met the accuracy specs they required on those units.


Some of the old resistors used dots of color along with bands. There wasn't a strict set of standards on anything but the actual colors. The way the colors were applied varied a lot between manufacturers.
