I have acquired a few porcelain CPR pieces with the green CPR on the dome and some have a number stamped on the underside. I have looked every where for days on the internet to find a cd# and price of these fine looking pieces to no avail,other than Ebay or other sale sights but that doesn't give me a true value only what people think they are worth in their own mind. Was hoping someone could give me a real answer.
Happy Hunting.
