Silver Plate Oval Platter-Windsor Chile W-P 10 Micrones--15-1/2" x 10-3/4" Oval--No obvious utensil scratches-no pitting-polished but could use a touch up polish for serving.--The backside has on scratch mark-I would bet someone made an attempt to see of it was silver on copper. Which still is unanswered. It weighs approx 2-1/2 lbs. which is a similar weight of another silver tray I have listed which is copper based. This tray has a 3/4" depression--The silver finish is in excellent condition. I have had this platter in storage for over 10 years wrapped to protect the finish. Not sure of the age but would estimate from the 60's or 70's. Just a guess.
