It was built with Aelle tubing (lugged), fitted with a Shimano 600ex 6207 friction non-aero group throughout except for seatpost and stem, Gipiemme dropouts and fork ends, and brazed-on top tube brake cable guides. I've looked through the archives and found no exact specifications on tube ID/OD and seatpost size for the butted vs. straight gauge tubing.

Would this be normal for the straight gauge tubeset or could it possibly be the butted version? I have read that straight gauge Aelle has been spec'd to a 26.8mm seatpost, but I have no first-hand knowledge of this.

I replaced it but there are certain details of the replacement decal that are different (the "A" lost its legs). Here are the photos:

According to my 1980s vintage Columbus catalog, Aelle is straight-gauge except for the steer tube:
