Old Time Baseball DOS Gameplay Washington at Chicago N with Curt Gowdy

Another game of Old Time Baseball on the way for ya! This is Washington at Chicago. Again, I am not sure what year the teams are, and what era of baseball is being played. But we have curt Gowdy on the call! Anyway, if anybody can tell what years the teams are, and what era is being played, please let me know in the comments, because I tried to set a game up by myself, and this was the result.
