A local gave me a pair of retrct gears mostly of plastic with SS wire legs.

Onna side is printed W.M. LG 3500001 as I asume a part number. The old fellow who gave me the pair (a Rt. and Lt.) said they came of some middle 1980's pattern plane he had purchased and did not fly for years afterwards.

I assume that W.M. means World Models, but cannot find an advertisment mentioning such. Did these ONLY come inside some kit then? or, is my assumption wrong?
