Hope this helps someone out there.. sorry not vespa related.. recently picked up a 20 plate lambretta v 125 off a friend his pride and joy until one morning.. some lowlife stole it . Smashed front panel plus frontal damage ripped out ignition said lowlife tried to Hotwire unfortunate scooter .. been having a lot of trouble sourcing parts even used .. right getting back to ignition unit crazy prices new anything from £95 to around £140 from the states.. after lots of google searches and looking at images.. A 2023 sym symphony 125 model 6 pin has done the job only down side it only has one pull function for the seat and not the glove box guess know big deal .. I believe the lambretta is sym based .. hope this helps ..
