I came into a set of original Powell Peralta 90A Rat-bones in mint condition. These wheels are yellowed with a dark brown 1/4 " wide stripe made into the center of the wheel. Any ideas of this?
The bearings that were loaded have these markings: SINGAPORE Z809 NHBB all silver in color. Any information about these bearings would be appreciated. The retainer rings are metal, not sure if they come off.
