I have a chance to buy a very old track bike and I was told it was built by Oscar Juner. Does anyone know if he built his own frames? I know he was a six day racer in the 30`s and owned a bike shop for 50 years in San Fran but did he ever build his own frames? Did he have someone else build frames that he sold in his shop? Thanks if you can spread any light on this subject. Anyone have any pictures of his bikes?
