Neither Aelle nor Zeta employed the patented Columbus steering tube and therefore would not have the Columbus dove logo stamped on the outside or the five helical ridges on the inside, at the bottom.

I think the 26.8 post size is correct; it came with a post and I'd have remembered a 26.6 post as odd. I know there were no markings and/or ridges on the steerer.
T-mar, quick question; I have an Olmo (late 70's-early 80's)with a 26.8 post, but a lighter frame. Is there another Columbus tubing that would require that size seat post, or might it be improper finishing/reaming?
DD, it does look a wee bit spread from that photo. Making a note for when I pick it up.
Next mystery frame is hanging in the garage waiting for identification; it might be the toughest one yet!
