He sold it to a pal of mine who was new to Lambrettas who didn't really know what he was buying and over paid for what was mostly junk. Frank told me what the external pins were for but I cant remember now. probably like you say an external disc.
I ended up with it, decided it looked ok but couldn't be bothered to do anything with it and sold it at Kettering about 4 years ago?
Thankyou for that information.
As I recall, I'd been to a 'niter but wandered the 10 minute walk up to Wickies late in the afternoon with some spending loot, saw the 'set' (including an additional, unfinished WIP twin pot backplate) & it all looked well engineered. I reckon I just caught you ready to pack up & go home because I'd call it all a bargain. YOO WOZ ROBBED! Sorry
The twin pot backplate looks to me as if it could be passed off as an Innocenti 'special project' if you understand? The pistons are corroded, so I'll search out/turn up some replacements in stainless, though the whole assembly can be made more shallow IMO. The seals all look good & I have a Kelgate fully vented & drilled disc that I got a couple (one spare) of conversion hubs made for. They fit the Innocenti three pin arrangement & carry the Kelgate disc via a six dowel pin arrangement.
Each to their own, but I have a spare external disc set-up in the garage, but the look doesn't appeal to me. Lambretta went to a lot of trouble to hide away much of the mechanicals for the clean aesthetic. More 'car' than 'motorbike' I guess. In any case, a certain Mr Edmonds went well enough with his hydraulic OEM front brake.....
