Congrats on scoring a very nice Frame! The merckx signature indicates that it‘s indeed a fairly early frame. However, the short lugs, bottom bracket and the area around the seatpost bolt are all details that weren‘t present on the earliest frames. My guess would be that it‘s from 1981 or 82. This model is often referred to as ‘professional‘ on the basis of an early catalogue where it says: professional road model.
However, in the flamish catalogue, the same model was denominated as
‘Weg beroepstype‘, thus indicating that the term ‘professional‘ was not really a model name as such.
Good luck finding the matching pantographed brake levers, chainring and stem!
