I was stoked to get a 14/28 freewheel working on my 1972 ItalVega for last years Eroica California event. With a pat 72 NR dereailleur and 52/41 front rings everything is happy. I showed Wes who at the time was helping with the event and he told me 32 is possible if you remove the axel stop screws and pull the wheel as far back as you can. I have not tried it but I am tempted as I live on a hill and am now running 28's on a couple of my bikes. The other bike running a 28 just got switched to a patent 82 Super Record and it works perfectly , big to big , no problem.
