7005 is an Easton proprietary alloy developed for their baseball bats. Early 90's 7005 tubesets were very expensive, and still is here in the states. The Asians struck a deal with Easton but was not until mid to late 90's did 7005 frames come from Asia. From the look of the frame and considering the age, I still think it is high end.
I agree, maybe just Euro market.
Don't assume 7000 on the sticker is Easton Elite or something uber fancy
I like everything you wrote except the part about mid to late 90's. I know its splitting hairs, but I'm throw in a few years before that. My Nishiki Alien was 7075 as I recall, and imported from Taiwan. Regardless of the arguments about which is stronger than the other as a material, I'd still say it's a safe assumption that the better bikes were made by smaller manufacturers out of 6061, and the big frame pumpers in asia prefered 7075.
I can't think of a top shelf aluminum frame from the early 90's, made from 7075 at all...
I guess what I'm saying is there's a big difference between Easton's 7005 and run of the mill Asian 7075 et al. Not all 7000 series aluminums are created equal.
Edited to clean up the mess and to make my point.
