Technical Cadillac Lense Help Please

I have one Cadillac Conaphore Type F lense. It's 9 1/4" OD and has 2 chips on the outside edge and, has some scratches. I'd like to post it in the classified section but, I don't know anything about it. Anyone know what year it is and is it even worth anything? Thanks in advance.

 

I don't know anything about it either, but i'll bump it up for you.

 

Any help???

 

you could post it at the Early Cadillac Groups website,that is very old,possibly teens or older,i am sure someone there would love to have it,google the Early Cadillac Group and it should come up. Harvey

 

Thank you 37 caddy.
