Yes, Huret made toothless jockey wheels. The wheels also had ball bearings, so they worked great.

Motobecane never supplied bikes with Dia Compe brakes.

As for what to do with the bike, I don't know. Part it out? Frames sell for surprisingly high prices, even basically worthless frames like these. You could start an ebay auction at $20 and see where it goes. If you get $20 for it, you've basically broken even, and anything else, for the frame or parts, is profit. You may find something on it worth keeping.
