H class destroyer Hereward was the only H class at the Coronation Fleet Review 20 May 1937 at Spithead.
Here she is http://www.tynebuiltships.co.uk/H-Ships ... d1936.html
but none of these images are as she was when completed when she did shipboard trials during 1937 with the new twin 4.7" as fitted in the later Tribals, J, K and N classes.
At the Fleet review amongst others were all 9 B, all 9 E and all 9 G class were present, 3 full flotillas. All 9 D class were absent. Visually all the A -I classes appeared almost the same.
