Columbus air was around in 1982 at least, maybe a bit earlier. I have a Hujsak aero that was made in 82.
The review of it in bicycling says that the profile of the stays and top tube were Changed for 83, but I haven't seen any details of what was changed.

A lovely bike indeed - and it reminds me.
Can anyone on the list say whether Columbus Air tubing is on-topic?
I suspect not.
I only ask because in my stable a I have a "Bill Nickson" made from this tube set (who built that I wonder? - not Bill 'cos as far as I know he has never been a builder). As it's a lo-pro time-trial bike which apes the Lemond TDF winning machine - it's almost certainly off-topic.
As a point of interest, Columbus Air of course needs it's own dedicated seatpost, and as the one I got with the bike for a joke low price (off good old ebay) came with a badly graunched 'post - it was a nightmare sourcing a useable replacement.
I could find none in the UK but happily a CR list member came to the rescue and sold me a new 'post which of course had been 'born' in Italy, crossed the Atlantic to spent some time NIB in a shop stockroom in the 'States before travelling back to Europe to me in the UK...
