Hi Fred,
Recently re-worked an Atala I found on CL which was also a
1971 Atala professional. Seat post is 26.8. When I removed the red powder coating
and took her down to her birthday suit.
There were Columbus logos stamped into the 3 main tubes.
Disregard the upside down decal on the down tube, an issue with Guinness
that has been resolved.
