Thanks to everyone for the advice on how to clean up my Hartsfields and make them presentable. I decided to lean toward doing less than more -- I just cleaned it (I've only done one so far) with mineral spirits and waxed it with paste wax. It's a long way from perfect, but I think that it's OK even with its flaws and it's still original. Again, thanks again to everyone on the Board who helped! Now, I just have to get around to cleaning up the other one...
