Anybody know the brand?

 

Can you get a side angle so we can see the complete profile of the retainer?

I will say this, every aftermarket retainer I've seen doesn't have a machined dished top, so that might make them super easy to id, or completely impossible

 

m a try and get it apart tomorrow thanks I and leaning towards manley, but cant get a pic of the top of some only thing I found online that looked like them was "howards cams" which I never heard of.
