Wow, that's a neat find for $100! For an obscure brand, sometimes details are hard to track down, but that also makes your project even more unique. For refinishing, I'd suggest starting with a gentle cleaning and then assessing the body for any damage that needs repairing before you dive into sanding or painting. If the electronics work fine, great! If not, considering upgrading them could really breathe unique life into it. Can't wait to see how it turns out – make sure to post before and after pics!
