Yes the loopies originally came in 32" and shortly after 28" sizes. That's why we believe they were used for a while, at least first 800 or so units until the hat rims appeared. The first MPC (Master Parts Catalog) for the Ford-Ferguson 9N Tractor was released March 15, 1940. We have it here as a FREE download in our MANUALS forum -see LINK below. It lists both 32" and 28" Hat Rim style but no mention of the Loopies.
