These are scans of original (and rare) brochures and leaflets, they are full of 

useful information. To keep the loading time to a minimum, I have reproduced

them below in a small format. Where text needs to be readable, just click where instructed

and you will get a large (readable) version of this area - this will take some time to open.

Click the page or the button on the left.

The page above shows both the model 45, on the right and the 55 on the left.  These are the models as of about mid 1980's.  Note the pics on the page show the steel fuel tanks, where as the lower diagrams depict the correct plastic tank of the later gulls.   pic courtesy of Greg Taylor of Queensland.
