The chain rings are 130 BCD so there are many options available, but (as Cyclotoine said) the smallest you can get is 39t so that won't make a big difference. You can, however, get a wider range freewheel. That early Dura Ace stuff is really nice; I wouldn't let anyone talk me into "upgrading" anything other than, maybe, the rear derailleur (so you can fit one with a longer cage, to suit a wider range freewheel).
I have a mid 70's Fuji 'Ace' that has the same stuff, and I ride it over some pretty good hills.
