Custom I think.
Tim

or not, sorry, thought it would have been some use but doesnt look like it

Well it’s almost certainly custom, but there are those 70s retro fonts to consider (the look reminds of the article about the font for Mexico ‘70 in dotdotdot).

You could try ITC Bauhaus in the lighter weights; Blippo and Churchward also carry similar characteristics, but I don’t know if they are digital fonts these days.

You could always try posting a message to Bruno Maag, director of Dalton Maag, they designed the new Puma typeface for this years world cup.

Might be possible that he would have information on other sports type design.
