Help with ID and age of this glass lamp shade

I found this beautiful shade and was hoping to find out if it is antique?
Real thick heavy glass mo marks, the Amber satin finish I think is applied as there is a lot of scratches and what looks like small areas of peeling. 7 3/4" bottom fitter.
I thought it would look good on my 1880's Sears Roebuck eapg lamp? But not is it is from the 1960's lol.

Wondering if someone gave it a light spray color............?

 

Could be. I've found the same shade searching but only clear ones.

I found one very like it, but the seller doesn’t know anything about it. Except that it’s quite pretty. Which we already knew
