I found the pictures of this nice example of a TR4 as a rally prepare car on: https://stevemckelvie.wordpress.com/2011/08/02/the-triumph-trs-the-triumph-tr4/ . They were taken during the Maple Leaf Winter Rally in February 2011.
Besides the fact, that it is a very early car (production number 217), I want to share the photographs with you, because of the very unusually after market hardtop. It seems to be longer, very cloe to the filler cap and the rear window hasn't got the styling the Surrey-Tops had.
It is a good example on the variety of hardtops, available for so many of those British sportscars, from there own designs, fastback or bermuda to imitates of the ones, supplied by the factory.
