Okay, so, the wheels I found on FB Marketplace - They're not Dura Ace 7200. I was wrong about the acorn nuts - I guess I saw what I wanted to. BUT they are tubular rims. In fact they come with a pair of Wolber tubs, which hold air. Well SOME air. But they're no longer glued to the rim. The hubs appear to be first generation Shimano 600s, 36 hole. The rims are Mavic Monthlery Pros, in good shape. There surface rust on some of the hub components but the rear spins smoothly, and while the front is a little 'crunchy', it may still be fine once repacked. We'll see.
The wheels are almost certainly 120mm, and I need 126 to fit the dropouts on the Lotus, but I figure I can get there with spacers, maybe a new axle, and of course re-dish the wheel. Now I have a project for my new truing stand! That and learning how to glue tubs.
