@AJ 1967 No problem. You have enlightened (and interested) me regarding "newer" Olmos as my present model is substantially older (and also hard to ID), and before they started using more of the various Columbus tubesets on the market in the early to mid '80s and beyond. I am somewhat perplexed that I cannot find (I never really tried researching it previously; I have none, nor have I worked on an "AIR" frame before) a spec sheet for the "AIR" tubeset given that is was in production for at least 4 years (maybe 5) by all accounts and was used by a variety of builders during its lifetime.
Unfortunately, I can only hope Columbus' records will reveal some information, but as with many Italian companies I have reached out to, it often seems like they know nothing other than some generalities about their products in the '80s and prior to that time (Colnago being the worse!). I have other questions to ask them that are unrelated the "AIR" product so hoping to clear up a few other things that remain unanswered for me.
I might pose some questions to "SAARF"; but I have seen information provided by him that contradicts known facts, and he is not easy to get along with (can be downright rude!) if you question his "authority" on certain subjects, but still worth a try since his experience had some merits.
I think your example from "RSC" is a great bet as being pretty much definitive for what is available at present. I have found that site to be a good resource for a lot of my older bikes from the '30s to '70s (although I still have a couple mystery bikes; I never really used it for "newer" bikes post-'70s), and contributors are usually quite knowledgeable as to the history of their machines when providing examples to add to that database.
