Congratulations, Danger on your purchase.
I bought one of those closing-the-shop units back in the mid-90's. It was scraped and rusted. Took it all apart and had it blasted and coated with an offshore platform epoxy coating that we were using for some North Sea equipment at the time. Dead ringer for the original Handy "machinery grey", but REALLY tough. Bought a bunch of new seals, bearings, and parts from Handy (including all the original stickers) and made it like a new unit.
I would recommend one to every bike owner out there. It's the best. You will wonder how you ever did stuff without it. It's so sturdy and stable, you can sit on a street bike when it is raised up on the table, but I would NOT recommend that.
