The really old Maillard freewheels used the same two-notch system as Regina. This later changed to a splined system shared by Zeus, Everest, and others. Schwinn used some Maillard/Normandy freewheels with a larger splined diameter. After Sachs purchased Maillard, they adopted the Shimano spline pattern. But none of my Maillard tools look like the ones in your picture.
That's interesting to know about the threading. So I'm guessing the maillard freewheels that showed up on schwinns used ISO threading? The oversize schwinn tool you have there looks like it might be 24 spline...perhaps it's a slightly different look of the same tool I posted on the left?
This link has a little more info on the left tool, and mentions it's used on some schwinns. The tool I posted on the right I can find almost nothing about.
Also interesting to hear there are some maillards that had shimano splines. Thanks for the reply.
