Yup, mine came out in one piece & features a label:
Warning! Pressurised Unit Do Not Open etc. also there's a serial number AT5 100283, I guess they made at least 283 then!
Shows the name: Cycle Suspension Ltd England
Does anyone know if it's possible to get the unit serviced?
This one seems reasonable condition, the grease looks like it was left over from the bottom race rather than a leak. Paint's a bit scuffed. I suppose that means I'll have to keep the frame with it, I'll put it in the pile with my other 'retirement projects'.
