Not seen these before (although there seem to be a few listed on the Italian eBay site) Pop-up or ‘semaphore’ indicators for a Lambretta (or a classic scooter anyway). They remind me of the ones I used to have on my old split-screen Moggy Minor. I think they’d look good on a restored older open frame model (A-F), or an LC or LD.
You’d need deep pocket though – they’re priced at €2,000!
