Cease and Desist is one of the only companies that makes football shapes, but they are knockoff wall hangers. I don't know how skateable they are. Most of the others mentioned are proto-footballs--smoothed out '80s vert shapes that are widest near the front foot and have squarish tails. A true football shape widens out more towards the middle and has a thin nose/tail, optimizing it for flip tricks (the fucked up Blind series and most Blind decks from late '92 to early '93 are spot on).
Socal Skateshop has a Krooked Drehobl Zeroks deck that is kind of close, but is a hybrid of an '80s shape and a football. I thought JK industries would definitely have one, but then remembered that Klein's shapes, even back in the day, were a bit of a throwback (wide near the front with blunt noses). Perhaps JK will make a small run of true footballs if there is demand.
