It was called GKN Mills ( no yellow ) blue and white, I started with them in 1973 at their West London Branch. Some time in the 80's the name changed to GKN Kwikform, which did not go down well with the old school scaffs as most of guys I cut my teeth with were Mill's guys. The Kwikform came from their new product " the dog bone system" as we nicked named it, still no yellow just plane and white, I'm working in NZ at the mo, if and when I get back to the UK, I'll dig out some pics of the branch and see if there is a logo in site.
