I still have my Houdaille Road Machine. As far as a trainer goes, it is comparatively quiet for the era and had the added bonus of not wearing on a rear tire, thereby leaving the room without the scent of rubber as well as the attendant very small rubber sooty pieces, which is really what we breathe eventually. The bike had to be 120mm at the rear so as the thing would fit.
Since I now ride outside, climbing on my MTB in this hilly area in winter, or use a Kettler machine that allows me to train with watts, I would consider parting with the Houdiaille if any CRer might be interested.
