I just picked up this Eddy Merckx today off of CL listed as an "Eddy Merc". I believe it's a 1985 Corsa Extra based on the SLX tubing and the Z above the serial number. Any ideas on the year and Model? I purchased from the original owner who said he was a CAT 3 Racer back in the day and used it for Crits. He swapped out most of the original Campy for Dura-Ace and a Control tech
