Valve covers on ebay

[JoeC]

Frank, unfortunately they look like the ones being sold today for approx. $100.00
Nothing wrong with them just should only have paid about $100.00.
The newer ones seem to have better polishing job then older ones and some older ones are not polished.
The early 70s Motion valve covers that I have seen are chrome plated aluminum and have a different style Motion emblem. Then mid 70s were chrome plated with new style Motion emblem, then later ones were polished aluminum. The mid to late 70s catalog offers chrome or polished. In the early catalog only one type is offered which I believe was chrome plated. This is from what I have seen in old pictures in catalogs and magazines.
attached is BB and SB ones I have that are chrome plated alum with new style Motion emblems which I estimate date of mid 70s.
