Hi mate, funny you should say that as i've just put mine down!
I also would be interested in an online source. I guess i could photo copy my one and send to you? but in todays age of technology I cant believe that their isnt a pdf somewhere.
The brochure is good for identifying part numbers, I do my sourcing from these.
Im after a set of air tubes next if you know of any.
Give me a shout on the photocopy offer.
