Production Details and Changes
The date and times of when changes happened with the GP can be a highly debated thing. There appears to be not one change point, but the changes listed happened over a period of time.
On the forums there is a section for people to be able to chat, debate and find out more detail and information from each other.

Frame 258***
Onwards
The frame loop was revised with bigger holes for the rubber mounts (grommets) to go through and there is a revised plate that is welded to the end of the coil/frame support tube. This plate has multiple spot welds and revised cutouts to allow easier fitting of the rear light mounts and large hexagonal 'thumb screws'.
Unknown If you've ever bought an original early Innocenti GP you nearly always find that the light unit has cracked along the stud line. This revised design for the rear frame (above) was obviously intended to aleviate this design flaw. There is also an original letter from Lambretta Concessionaires telling UK dealers to fit rubber light gaskets to GPs that come in for service/work in order to reduce the number of owners suffering light cracking problems.
