I didn't go with tubulars on it, but I recently got done building up a 1977 Argos that had plenty of width in the fork, and I was contemplating ordering 32's. In fact, had the ones I wanted been available, I would have gotten them, so I settled for 28's. As it is, the 28's are about all that it will take.
I think 25's or 26's are a good call on your machine.
