Hi Dan, I have a unit. A friend's husband died a few years ago, and she's finally cleaning out the darkroom. I have a Beseler Motor Base. It's a little dusty, but I plugged it in, and it works: the two large wheels do turn. It only goes in one direction; there is no reverse switch. Let me know how much it is worth to your friend, including shipping.

Tnx,

-- Mark
