The actual 'Giftware' models had two fixing points and this cured any of the above from happening and my baseplate has two fixing points, in the exact place as 'Giftware' models, however, my particular example as shown in my pictures, has an earlier detail specification than my earliest plated 'Giftware' model, which is dated as 1961 production, with black 'Knobbly' tyres and a flat rear boss, (the plating process being developed during 1961 and trialled on some Bugatti models first), so, is my example an early proper 'Giftware' model or a 'plating' trial model.
Asuming my model is no longer an 'Anniversary' model, when was the actual 'Anniversary' model made...maybe Bob can be coaxed again into providing some more of his excellent pictures of his example, specifically the steering wheel centre nut, (looking from the side, not from above) and the R-R grille badge, (this should be of the 'wide' design, if the badge is of the 'narrow' design, that pre-dates everything 'plated' in my collection!) and a few more general shots would be nice...sorry Bob if you've already put it away from your last photo session...
