Back in 2007 Dean's Marine sold Rob Kernaghan and me the assembly instruction plan for their kit of ASW frigate type 14 HMS
Hardy:

Along with photographs of actual ships, the above plan satisfied me as accurate enough for my model.
http://finewaterline.com/ has a page in its gallery of small warships about how I modeled HMS
Palliser. There you can see the Dean's Marine plan in small scale with my mark-ups for fabricating PE parts.
Despite fax-quality resolution, the most accurate drawing I found is in Norman Friedman's
British Destroyers and Frigates, the Second World War and After.
The Dean's Marine plan represents, I believe:
Dundas, Hardy, Keppel, Grafton, Murray.
Pellew, Russell, Exmouth, and the three Indian navy frigates featured larger but fewer windows in the pilot house.
Blackwood, Malcolm, Palliser, Duncan featured the same larger windows and initially mounted two pairs of torpedo tubes for Bidder ASW torpedoes.
Exmouth was reported as mounting the Bidder tubes but I never found a photograph to confirm that.
In the late 1950s the Bidder tubes and the aft 40mm Bofors gun were deleted from the RN frigates.
