The drawing below, as marked, is of HMS Javelin as completed in 1939. HMS Javelin is what I would call the base unit for all of the other members/versions of the JKN types.
I have been given the 'Design Process' drawings (6 of them) for the J class and that is my next project.
Anyone who wishes to use this base drawing to produce HMS Kelly (the most famous of the class), the Aussie 'N's, or any other of the class, is quite welcome to do so and add them to the thread.
Please note: the COA is not the real one, but one I have done to act as a placeholder till the real one might become available.
The COA has been replaced with the real one. Thanks to Kim for his help. (any mistakes are bound to be mine)
