Thanks for the advice. I just picked up another machine today. I couldn't resist. I got my first Vendo H63-A in full working condition no major rust but a few dings. Nothing some body work and paint can't fix. Then today, from the same guy I got a Cavalier USS-8-64 in full working condition with no rust and no dings. Actually a great cleaning would be enough. Both units for $150.00 each. I thought it was a decent deal.
The USS-8-64 is probably the best of the square-top machines overall. Definitely one of the most versatile. I have one in my garage and was happy to have it for double what you paid for yours. Well done!
