Just got this from a local club member. It's an ex-team drivers Works 91, originally run by Jimbo Pearson, fitted with all the parts developed by CML for the team drivers. Changes are the following custom made parts for the team drivers: short front wishbones with Optima knuckles and C hubs, machined nylon front gearbox, front shock mount, top deck, steering pivot brace, heatsink motor mount, custom layshaft adapted to fit Associated Stealth slipper clutch parts, 3mm belts and an adjustable tension one way to vary brake bias. A lot of these parts ended up being included in the works 93
It came with the Losi Hard Body shocks fitted as seen in the photos. The Associated factory team shocks that were originally fitted were included, unfortunately they are missing the shock caps but not too hard to get hold of.
The awkward parts of restoring this will be finding a Works 91 body and more awkwardly replacing the custom machined adaptor to fit the stealth slipper to the rear belt pulley, it's not fitted because the soft aluminium pulley has worn out. It should be made easier as the part was later included as a Yokomo part in the works 93, part number ZC671 if anyone has a spare, although it would be nice to reproduce the original part.
Got a big box of new and used spares included with it so most of the restoration should be easy.
