Smallest made 5-pin by Campagnolo was 35t but Chris Bell at Highpath Engineering will make you a 34t. $109 + shiping. He can make you a 34t 116mm 3-pin as well. Same price.
Why not?

most common is the 144 BCD which is essentially a Nuovo Record with not
quite as fine a finish. Next most common is the 3-arm 116 BCD GS which
was OE on the Raleigh Competition GS. Most obscure of the three was the
late (early 80's) 5-arm 116 BCD. This one uses the same rings as
Victory/Triomphe as already stated. The 144 of course takes a 42T ring,
or 41T if you can find one. The 5-arm 116 was made in 35T although
these are a bit rare - 36T are pretty common. I think maybe
theoretically a 116 might be able to take a ring a bit smaller than 35T,
which would apply to the 3-arm 116 BCD as well, although I've rarely
seen a 116 3-arm ring smaller than 40T. I believe the 3-arm GS rings
are interchangeable with 3-arm TA, Stronglight and perhaps Nervar.
