SERIOUS buyer for vintage Goodyear Industrial inner tubes

Used between the data recorder and the box it was in, mounted in the trunk of the #88 Daytona, Petty's Road Runner and the MoTown Missile Duster and Cuda. I'll dig up a pic of the Duster and post it.

With the black box cover off, you can see the inner tubes. I have THAT box and the reel to reel recorder. I have 4 inner tubes and need 10 more. Hope you can help. Thanks!
