Hello Charlie, Plafit made a few Crowns for 3mm axles (same .5 module pitch as most of the modern plastic Crowns found on Slot-it,Scaley, NSR etc.)

I believe that a 28T was their smallest tooth count,.......google Plafit PL8531A.

Sigma "BRM" also has a 3mm Crown in a 30T,...............google Sigma S-027S30..........


Scaleauto also make some 3mm Crowns, but their smallest tooth count is a 32T.
