Hello Tommy, Greetings from a new uk member.
I've never seen that earlier style nozzle in '90' green or a hose of that period with a '55' type hose handle. '90's' are rare beasts, let alone in that condition ! Well done !
I was also lucky in Dec on ebay: a fine Z11 requiring little work doing on it. It has: box, spare boxed filters, instructions and what appears to an advertising flyer but sadly no floor brush and angled elbow !!
Getting back to your 90....I actually remember that model being demonstrated at the ideal homes exhibition when I was 6.......how I wanted one as my Grans early 65 seemed dated in comparison........I got a bike for Xmas !!!!
Congrats, Regards,Walter,Newport,Shropshire, UK.
