Just a quick update on this: I've arranged to obtain a coupon of wing
skin material from a local L-13 wreck, and arranged for a lab to do a
chemical assay to identify the primary alloy components. I'll also do
a static pull with my tensile test machine to get basic physical
properties.

Thanks, Bob K.

Thanks Bob !
Best Regards, Dave

PS: Are you going to do an analysis of the rivets as well ?
Composition, taper, hardness, etc ? For the hopelessly
curious...
