Townmate paint

Dont know about original paint code, but Hammerite Smoothrite is as good a match for the blue (assuming yours is blue)
Its available in tins for hand painting or rattle spray cans. It also has the advantage of have a rust preventative in it. Even better if you use the Smoothrite primer. http://www.hammerite.co.uk/products/direct_to_rust_metal_paint_smooth_finish.jsp

Yep. I used the blue on my T80 and it looks pretty good for a hand painted finish.
