COWECO "MODEL W" or "MODEL WX"

[TubeType]

I am trying to locate an available COWECO "Model W" or "Model WX" coil winder. This winder is sometimes referred to as a Wave, Universal Wound, Criss-Cross, Zig-Zag, Basket, Lattice, or Pi Winder. The "Model WX" coil winder is a dual-lateral progressive model, with a variable transmission for experimental designs.
Your help is greatly appreciated.

Thanks,
