How would one get hold of a 737 rudder servo valve
I apologise if this has been brought up before, but I'm yet to find any information upon it.
As part of a uni project I'm investigating the defective 737 rudder servo from the original and classic 737s. Research says over 2,700 were replaced by November 2002, and I'm trying to get my hands on one.
I've contacted a number of companies but am yet to have any joy in locating any. Does anyone have any idea how to find one? They are a relatively small part, I imagine if anyone were to keep a part they've stripped this would be it because of its conviniet size.
I hope someone can help, Thanks in advance.
