Be careful with the scotch brite pads. I have a Hercules of simular vintage that was rattle canned. I thought I was being careful enough but discovered that I was removing pigment from the box lining. The result is that the lines remainded but just enough that I can see to have them repainted. If I had it to do over again, I think I would have taken a gentler approach. By the way, what a cool find!
