I think Bakelite is another name for cast phenolic resin which is what billiard balls are usually made of these days. There are lots of collectible billiard and pool balls but I don't think I've ever seen a high price for phenolic carom balls.
Bob, The red looks very red, but the two whites are very brown with little squiggle lines all over, very feint. Never saw them this brown. When I can will take pictures of the ivory and these three. Thanks for the help.
