hi there
As has already been mentioned – there are a set of plans for HMS Exeter from My Hobbies Store. Personally I would class the available plans as semi-scale because there are several errors in the drawings. HMS Exeter is drawn as after her major refit – after the Battle of the River Plate.
There are several other sources of plans for Exeter on the World wide web but how accurate/ expensive they are I have no idea. The Maritime Museum in London hold plans for HMS Exeter, but, the majority of the plans for her are as she was to be built originally – before the final alterations – in other words she was to be built with 3 funnels and a tower bridge, similar to her sister HMS York.
As far as the other sets of plans, HMS Ajax/HMS Cumberland are concerned – there is a set of drawings for these ships – and they were drawn by Norman A. Ough which again are held in with the sets by David MacGregor which are held by SS Great Britain Trust. Where they are in releasing them for sale to the general public, I have no idea cos I have heard so many stories.
If you have a look in my albums you will see where I built HMS Exeter from plans from the Maritime Museum also a lot of personal photographs.
Hope this is of some help.
