Merckx owners thread

So can anyone suggest what year this Corsa Extra frame would be from? I need to make a decision between building with 8 or 9 speed Campag

Serial number starts with G. Vendor said the frame is SLX

Hilly Ben,

If you want to know if it's SLX or not shine a torch or something down the seat tube. if it is indeed SLX then you will see some spiral grooves like gun barrel rifling especially down at the bottom bracket end.
