Thanks for all the info Shane. Actually, the 3 spots on the motor board are shallow holes that somebody decided to drill or hit into the wood. I filled them with mahogany wood putty and they are way more visible on the photographs than in real, probably because of the flash. Don't know yet how to fix that better. I plan on having the tonearm re-plated at some point, but I'm not so sure about the back bracket. I think it was nickel plated on some, but black enameled on others. Even in your catalog scan the back bracket looks like it's black, not nickel. Regarding the corner of the back moulding, that is one of those cases of "is it part of the history of the machine or should it be repaired?". Knowing my limits in wood working I think I would make it worse if I touched it, so I'll leave it alone for now. Someone with better skills than I have can still fix a scuffed original, but there is no way back from a bad replacement. And I doubt that I'll have a class M anytime soon.
JPGs are great, I can still make them into a pdf. If you want to create PDFs easily you can use free tools like doPDF or others, they simply install as printers in Windows.
Thanks again
Andreas
