Doug, thank you for scanning those, I appreciate what a faff that can be, seeing period literature is always a treat!
Alistair, I literally LOL'd at the GL777 page, I could do with a pair of baffies like those, with a quilted nylon housecoat to match, hehehe!
I've always looked at Goblin vacuums as being a bit basic and not terribly well thought out compared to Hoover or Electrolux, or even their Teasmades, with details like the lack of upholstery nozzles or dusting brushes on many of the cylinders, and the lack of standard paper bag fittings on the 102 etc letting them down. Having said that, I have never been properly acquainted with a Goblin (no comments please...)
Having said that, I've always thought the Housemaids were quite striking cleaners, those along with the HP Swallow made Hoover's uprights look terribly old fashioned. Looking at the GL888 in particular, it looks like Hoover totally ripped off the dust collection arrangement on the Turbopower/Turbomaster Freedom Permabag, 20 years after the Goblin design!
