The scooter came from the inner south of Melbourne and popped up on Gumtree. In Australia there is a national scheme to track written off and stolen vehicles and the scooter does not appear on the register. Vehicle titles do not exist down here but I have a registration transfer receipt in the seller's name.
This scooter according to the owner had been stolen and was recovered after a few months being used to ride around in "the bush/forest". Looks like the thieves had levered off the horn cover and then drilled out the lock while retaining the ignition switch. A coat of semi gloss black over the wiring loom and most of the scooter completed the "rebirthing"
Spent an hour with a sanding block checking bubbly spots for corrosion. Fortunately most of the blistering is a really poorly prepped paint job. There are no keys and the seat lock is missing with signs of a brutal removal. If I was betting man the glovebox was unlocked when it was stolen as it is mint.
Most likely it did come from Vespa House but sales of scooters were really low in the 90's in Australia. In 1992 a grand total of 18 vespas was sold across all of Australia and they seemed very primitive compared to everything else on the market. 1996 was when the ET4 was released which just made selling a scooter that was effectively unchanged for 10 years even harder.
