^^^^^^^^^^^^^^
The drive I remember did not have flanges on the pulleys--it relied on
crowned drive surfaces to keep the belt centered. The only reason I
remember this is that I remember being puzzled about why a belt seeks the
highest part of the pulley. This was about seventy years ago, and I am
still puzzled by this question.
