General Information
These hubs have been identified as from the Gran Sport group, likely from the mid to late 50's.  Unfortunately, they fall in the time period between the #13 and #14 catalogs so I have very little additional information on them.  Steel hub bodies with pressed on aluminum flanges.  Note the very squared off outside styling of the flanges down to the dust covers.
