Zane,
May I suggest you first separate Lancair from Columbia because the several Lancair designs of Lance Neibauer are all Experimental class homebuilts? They were so popular that Neibauer sought FAA certification of improved designs he called Columbia, the 300, the 350 and 400 that had engineering designations far more esoteric that the FAA uses. See my examples from my Home page.
Columbia was purchased by Cessna after Columbia's financial demise due in part to heavy losses of new aircraft outdoors in Oregon with hail damage on the composite molded surfaces and the models are now called by Cessna the Cessna 350 and the Cessna 400, simpler and more to the point. Cessna is advertising them as Cessna aircraft and keeping production in Bend, Oregon. So, I suggest a third category based upon who built them and how registered with the FAA-Cessna 350 and 400.
Lance got his aviation start at SZP, renting a large building just off airport adjacent to final approach to runway 22. Both artist and pilot, he designed the aircraft as fast cross-country speedsters. I have downloaded many examples.
