that old classic design used round section leather belts.

the modern day joinable round section polyurethane belts would be a

You are probably right. I can not see the photo well enough to tell
how the groove in the pulleys is shaped. But Vee belts are used in
drives that change direction.

I looked in W.W. Grainger catalog. They do not give those round belts
away.

Round urethane belts are reasonably priced at McMaster. But depending
on the load and the size and durometer of the belt, urethane may be
unacceptably stretchy. McMaster also carries round leather belting and
splices. Both urethane and leather are on p. 1031.
