Looking at the microfiches, it shows the H rad being a smaller rectangle, and the L being a larger curved one. Mine is a larger curved one, but where the pipe connects to it (under the cap) the tube is bent round to face the left like the H microfiche shows, whereas the L microfiche showing it facing straight out.
Should i try and find an H rad or an L rad? The L looks more likely to fit than the H.
