Does anybody know what alloy and thickness was used for the ribs of the 1949 Liner? A couple of mine have some collision damage (from before I purchased it) and therefore require or replacement.
An Airstream brochure from 1949 says that they are of the "same work hardening aluminum allow as used in the latest jet planes," and other details in that brochure refer to the crossmembers as .051 24-ST aluminum and stringers as 24-ST aluminum. My understanding is that the 24-ST aluminum is the same (or almost the same) as what is today called 2024 T3 aluminum. But it doesn't actually describe the ribs directly. Are the ribs / roof bows also .032 or .051 2024 aluminum? (I suppose I could buy a decent set of calipers to measure thickness.)
