WOOF! Lotta work for a bone! How about this? How prevalent were the Electrad red resistors? I found one of those attached to an old Pilot tin box cap(1930) that I rebuilt. Turns out to be a small cardboard tube the size of a drinking straw, with end caps flush inside. Painted red, then they put a little yellow paper label on it, with the name and value printed. I think I could make the tube from paper or plastic straws(last resort) and insert a modern half watt inside easily. Cap the ends, paint it red, and replicate the label sticker on my printer. I pulled the inside out, and it looks like a WW on some flexible core. Looks like a little red firecracker! Was that a common brand, or just made for certain types, like for power? OK on the value drift, perhaps they were all trashed long ago. Tnx for replies.
