Logan's remark "remanufactured 51-55* pearlite wheels" needs expanding. Pearlite was used on a lot of high end cars and not just KFs. It looked good for perhaps the first year. It was a formaldahyde plastic that oxidized, turned yellow, then cracked, crumbled, and finally turned to dust - and smelled disagreeable during the process. Carl Hering collected a number of pearlite wheels, froze them and then knocked the remaining plastic off with a hammer to get to the basic metal structure. The cleaned metal was sent off and new plastic was molded around it. The new plastic was not the same as pearlite although the wheel could be painted to appear similar to pearlite.
Well the cleaning was tedious and after initial demand was satisfied, he decided to end the project.
There never was enough interest to do the pearlite wheels on the early cars and that was partially because fewer of the early cars had them.
* 54-55 Kaisers had plastic wheels, no pearlite. The parts book says they came in different colors, but if anything other than black was used, they have not shown up at a meet installed on a car.
