I found a link after a brief search here. The tailwheel you refer to,
I believe, is the "Bob Wheel" after Bob Barrow the designer. You had a
post or two on the discussion so I assume it is the right one. Plans
can be found but there is also a fellow who makes and sells these
tailwheels for about $600. His web site is:

Thanks again. Don.
