4 Piece Silver Coffee Tea Set with Serving Tray. I have no idea how old this is, but what I can say is that it has been.
In my family since at least 1973. It has been collecting dust in the cupboard. Of my china cabinet for the last thirty years.
As you can see from the pictures, it polishes up nicely. There are a few black spots. On the tray, but the pictures wouldn't capture this.
The inside of the coffee canister is starting to show the copper. The inside of the creamer is also showing signs of the copper.
