Color Coding for Old White Brothers or Speed Srings Fork Upgrades

Hello,

Anybody know the Color Coding for Old White Brothers or Speed Springs Fork Upgrades?

Both companies sold coil springs for forks in the 90's as upgrades to elastomers. They painted the springs to designate their coil weight/spring strength.

Occasionally, I run across some, but the packaging is usually gone and so is the indication of spring strength, though the paint is still on the springs.

Thanks,

Pat S
