Gerry, you’re right, the only way to reliably deal with Solar cap restorations is to reproduce them from scratch. I don’t know a way to restuff them. Solar caps aren’t constructed from a cardboard tube but are molded from a brittle plastic or hard wax material, covered by a very thin paper label. I’ve tried drilling out the centre but just shattered the body material, so I took a shortcut here and restuffed an old Sprague as a replacement.
I’ve still got the original cap so will soak off the label, scan it for future use, and then repro a cap by applying the label around a new cardboard tube with a new poly cap inside. Another reason to go back inside this chassis and tidy up the details!
Do any other folks have scans of paper labels that we could perhaps collect on the website?
