Hemi Valve cover ID

I think these are moon covers but they look a bit different than the new ones. I just want to make sure what they are.

 

Not a clue???

 

Any ID numbers or letters on the backside?

 

No they don't but they have two reinforced bosses at the tops to put two breathers on each one. That leans me more towards early Donovans?

 

Those are complete junk. Send them to me...I'll scrap them out for you.

 

Look like Ansens to me.

They seem to be bringing pretty good money, no matter who made them.

Sort of like the Billetfab set listed as Donovan.

 

I know thy are sort of close to a lot that I have seen. The guy I got them from was a nostalgia racer and had tons of stuff. He was not sure what exactly they were but had not purchased any for quite some time. I would like to know so I can pass on the info.

 

Anyone??
