You are in my wheelhouse now, John. I collect these and have the entire set. Ask me any questions you want about them. It is a lot of fun to put together. There are 17 known premiums in the set.
Here is the one with Ace.
My understanding is that the R311 designation was selected by Jefferson Burdick to encompass all of the National Chicle Premiums and he used the "-1, -2" designation to distinguish between baseball and football. The baseball set is R311-1
