Why do you say anodising before 1980 would be F1 or NASA technology? It's been around for nearly 100 years and specialist anodising companies have been in existence for many decades, as you will see if you read the history of DAP (Dorset Aluminium) above.
It's a much more common process than you might think and i'm willing to say with some certainty you have anodised aluminium products in your house without even realising it.

Thanks for that. I meant really from a cost perspective. I know that now a days a aluminium framed bike at £250 is good. But from a cost perspective a good aluminium framed bike in the 60s or 70s would be a very expensive piece of kit (if it were even available).
