The Viscount (and prior to that, the Lambert) series of filet brazed Aerospace frames existed before the Super-Bike's release.
In terms of dates, I always presumed (by logic alone) that the Super Bike release was shortly after that iteration of the black Dura Ace group set. So in a word, the Aerospace didn't evolve from the Superbike. the Super bike just sat at the top of the tree in terms of price and components - although you could argue that for rarity and wow factor for Viscount enthusiasts the gold plated Viscount is up there.
It's a fact that Viscount marketing, production and overall 'strategy' was haphazard to say the least.
As an example, despite having a fairly big sample size of the frame numbers , it would elude even the greatest minds at Bletchley Park what the 'system' means . It follows no logic or formula. Really.
I see lots of posts on bike forums from new owners of Viscount giving their frame number asking for info. They soon realise that things are not simple where Viscount are involved.
I have a few anecdotes from people who worked at the factories who said they would finish up using older components on new frames and send them out , and also using older frames with newer parts, thereby making the range of bikes out there quite 'complex'.
There is also a frame that is half brazed and half lugged. That is another story entirely.
So, in terms of the chromed Super-Bike, it seems be part part of that 'logic' , that if they made a gold plated bike , then a chromed bike with top end components seemed like the next step, and why not?
