Not sure it is my place to clarify, but . . .
Chuck's design, built by Scud's choice of spring maker, was not "$200." That is the recent quote po18guy got from an aircraft supplier in the PNW/USA. That looks (to me) to be a "go away price."
Whether Scud chooses to use the last spring maker (took them twice to get it right) or another, IDK.
But, AFAIK, the $200/spring maker in the PNW is not the route of choice.
Check my work, and correct me if I am wrong. Just hoping to quell the confusion.
