Here is a set of 14 white and 14 red game pieces all from a Parker Brothers Camelot game from the 1930's.
The ivory colored pieces are made of Ivoriod and I believe that the red pieces are Catlin. All are in excellent condition. Four of each color are slightly larger with black tops. The black top pieces measure 1 1/8 inches tall. The 20 smaller pieces are about 7/8 inches tall. Diameter is about ¾ inch.
