All About Pocket Knives

I have a customer who wants a backspring replaced on their Case 6318 stockman. It is the single-blade spring, in carbon. Does anyone have one that they are willing to part with?

I have one from a torn up USA model I can send you. Springs are good but not much else good about it. Might be good to mic the blade thickness to be sure, this knife's master is about .091" at the tang. PM me your mailing info.
