Set 2 Vintage Portugal Copper Brass Saute Au Gratin Pans Heavy Scratching & Wear

Set of 2 double-handled sauce pans. They look to be copper with brass handles, but I'm not sure what the cooking surface is. They have a LOT of wear - please see photos. These are from my parent's estate, c1960. I have not tried to restore them. 

Etched "Made in Portugal R-46 "on the bottoms. No manufacturer's markings that I can see.

Each pan measures just under 6" in diameter. 

Please check over photos. I've tried to provide a lot of detail.
