Might this be the innards of an original door stop on a '24 OR so roadsters? It was wrapped with leather... that gave way, was re-wrapped some time ago... the re-wrapped on top with friction tape.
Not Model T
Someone added that style. The original would have been two footman loops and fabric type cloth (like the seat material) strap between them.

the rubber strap would have come later.
Very good... thanks!
