They look like the same people selling on ebay at the moment.
When I needed some paint made up, I took a sample of body (the broken bits!) to a local paintshop and they mixed up the colour to match. You may find that your local will do the same or can work from a paint code in the back of your owner's manual.
Have a search on
yellow pages for paint suppliers and give them a call.
Two large aerosol cans - enough to do a fairing - cost me 20 quid a few years back. The quality of the paint was really good too, none of the watery stuff you get from Halfrauds!
