Thanks for the information. I found this site
http://spookyshobbyshop.com/CADACO_a..._baseball.html this morning after I made my original post. For anyone who may be interested it has information including a list of discs that appeared in each year of the games production. Per that site this version was released between 1942-44. However it also says that the board from that year has one spinner not three. There seems to be a lot of conflicting information on these games. I doubt it has much value. But it was a nice gift and has been fun to research.
