While you can see from the advertisement below that the Fleet is a ‘divided diamond frame’ – the rear mudguard passes through the seat tube – what can’t be seen from the side profile is the nature of the design, which uses ‘channel’ or ‘trough’ tubing. When I bought this machine in 2016, I assumed it was a Premier because the Premier Model F is the best known proponent of this style of tubing. However, when I asked Roger Armstrong, the Premier marque enthusiast for the Veteran Cycle Club, he identified it as a Jackson ‘Fleet’. When I questioned him about the ‘trough’ tubing he explained that this was not a Premier patent, but a style of tubing that had already been commonly used on the rear forks of ordinaries, so was most likely without any patent.
