I have a few pairs of classic Belvini track mitts for sale. NOS from the 1960's/70's. These are the genuine classic item . Cotton string crocheted backs with real leather palms. Look like Ocana, Fuente or Agostinho. Perfect accompaniment to that classic cycle. Available in medium & large sizes pot luck on colours priced at a very reasonable $11.50 includes postage.
Best wishes and be lucky. Michael Butler Huntingdon UK.
