SSR Prototypes

Spot the difference Two SSR Winmesh adverts from 1981, the first, with the silver wheel, shows a regular Winmesh. The gold wheel has a Focus Racing style lip with 12 M6 cap screws and also has a spun centrecap. Seems like it may have been a prototype used for marketing materials

We've also got a 1980 advert for 15" SSR Mk2 and Mk3. The 15" versions of these models have always had a different appearance than the 13"/14" versions, but in this case they also have 12 rim screws instead of the 10 screws they're usually found with.
