If the smallest Stronglight mod 93 ring is 38T, it must be because the distance from the inside edge of the ring to the bolt hole is larger than necessary, like for a 151 Campy ring compared to a 144 Campy.

Stronglight ought to go lower than 38T. And, Bob Hovey wrote:

I distinctly remember putting a 36 on my 93.

Just a couple of observations: Not only does Sheldon Brown declare 38 as the minimum, but so does Sutherland IV. That takes care of authority, w/o even checking Cyclo-Pedia.
So, I got out a Stronglight 93 arm and an available 36 tooth (Campy, from the ugly triple) to eyeball the things. If someone were willing to do almost anything to get a 36 to run on a Stronglight, it would be possible. Of course, you would have to grind off the tops of the arms, down to just about the top of the chainring bolt hole (<1 mm clearance). Then find a ring that would sit on the arms - oddly enough, the Campy 36 is pretty close, maybe half a mm too big in radius.
For all that, the Stronglight 99 and its clones (86 mm BCD) do turn up occasionally, and have much greater flexibility.
Good luck!
