But a new FW won't "run" with the same sound as a 30 year old Perfect!

I agree, but if you don't want to throw away an old FW that could be re-conditioned for another 10,000+ miles of service, why throw it away?



They can look like new again!

Clean thoroughly, then reassemble using bead of light grease to keep the bearings in place.
Just open it up over a plastic container wider than the largest cog. Tip the container so all the balls collect on one side or in one corner, spray with WD-40, Simple Green, or concentrated Dawn dish detergent (depending on the degree of dirtiness). Swish until clean. Carefully place the balls on a paper towel, "massage" or roll until dry.

I also add a drop of quality machine oil to the pawl pivot.

I worked on a NWP for Jim Muller and it broke my Suntour Spanner Wrench!

When I've serviced the Perfects, they seem to self adjust just fine.

A few of my "Happy" freewheels after their time in the spa.
