AFAIK I know, the Mexican Windsor had no connection to any non-Mexican company except for the obvious copying of the Cinelli seatstay, and the various stories about how this came about, whether with permission of Cinelli, hiring away former Cinelli employees, etc. Well, one other "connection" was they persuaded (or paid or whatever) officials at the Mexico City velodrome to slap Windsor decals on the Colnago Eddy Merckx rode to a new Hour Record, a move that reportedly infuriated Ernesto Colnago.
What you describe sounds like an earlier bike of a completely different marque which has nothing in common with the Mexican Windsor but the name. This is not that unsual - there were for example at least three completely different bikes all called Condor. And considering their history in copying the Cinelli stays and slaping their decals on the Colnago, I doubt the Mexican company would have been shy about appropriating an existing name.
