lock up clutch cover

Hi could you guys tell me who made these type covers
Thanks

 

That was the first AFT, it was banned a very short time after, from small cracks forming in the cover. They then made one with a thicker cover, not anodized. I have used it for quite a few years with good success. I have one for sale if anybody is interested. It will certify. Eric Lourie

 

Crower makes one that is similar to that.
