I just took some measurments:
TT c-c: ~56cm
ST c-c: ~52cm
It is a Motobecane Nomade. The frame is lugged steel. I don't see any rust on it. I can't tell what brand the components are but it is a 10 speed. The wheels are in decent shape and appear to just need to be trued up. It would be a good candidate for a fixed gear/single speed.
If you or anyone else wants it, let me know.
