Stumbled over this posting, when I searched for pictures of seats in Italian delivered 73.
Interesting detail in the picture that Andrea posted is, that the driver seat hinge has no leaver and I guess also no hook to hold the backrest in position.
Have a pair of 73 double locker comfort seats with headrest holes plugged and no lever on the driver hinge, while the passenger side has the complete known mechanism in the hinge.
Had Italian spec cars unlockable driver backrest?
My 69E italian car has an unlockable driver backrest.
My Italian 73S #310, Oct 72, lock on the passenger only.
Here is a mention to an Autogerma but it seems incorporated in 1994
