Whats this engine out off ?

[super-se7en (Malc Dudley)]

eBay item 261126198151  says it may be trojan but it looks strange to me. Any ideas.

A transplanted Scooter engine which has been fitted to something like a Nobel.

certainly no link with anything heinkel/ trojan - but then he doesnt actually say it is he's just put them in the ad title to catch our eye - and it has  

but what the heck is it then ?

Hmmm... Chaincase looks a lot more modern than what I'm used to. Looks sort of lambretta like (not sure about engine though!). The suspension thing doesnt look like it belongs there. My guess is that it was a homemade thing with a scooter engine!

not even sure the heinkel like mounting bar is part of it - it doesn't seem to be substantially fixed if at all and it's not even mentioned in the ad. i had thought the whole thing rather earlier than later but possibly scooter rather than threewheeler . possibly the only part that is is the three wheels

Wheels are early scooter, be Vespa on size, I think, I have had some in the past.
