I figured we could do with a general thread for certain matters pertaining the Royal Dutch Navy instead of having multiple smaller threads enter the void of obscurity.

I'm working on two books. One pertaining Ship designs, which is currently in the stages of completion.

The other is related to the weaponry of all ships within the same period. It is a bit neglected recently, but it can be found here:

Anyways, now that I made a thread, I have a suitable place to post some design I found:
Firstly I have a blueprint of an De Zeven Provinciën class proposal.
Judging from the lack of the 57 mm battery and the pressence of 5¼-inch ordnance in Bofors turrets I reckon this is from ca. 1946 - 1947.

Next, I have found a Vickers destroyer of 1100 tons from around the early 1920s.
I also have blueprints of Thornycroft destroyers of 950, 1400, 1400 and 1600 tons and the Admiralen class version based on the latter.
Sadly, I have not obtained affirmative clearance to share the Thornycroft images. So I'll have to keep you in suspense.
The particulars of the Thornycroft designs were 3 - 4" guns and 1 - 3" guns for the 950 tons design and 4 - 4.7" guns for the larger ones, with each design differing in AA consisting of 2 pdrs, one or two 3" guns and a carried floatplane.

Bofors turrets for British 5.25s? Intriguing.

P.S. That one could become WG's Vrijheid, but why bother when you can just slap Oland's turrets on copy-pasted D7P hull... sorry, a bit of personal pain from a weirdo who still seeks historicity in WoWS.

I think they wanted to make the guns 5.25-inch to make the guns accept British pattern munitions, though I cannot at the moment find any mention for this being specifically the case. It is most certainly distinct from the British Mk IIIs they had on other blueprints.

Also while Wargaming uses the name and values for Öland's turrets, they actually use a butchered model of the 12 cm №9 with an extra trunnion outside of the armoured protrusion made for the trunnion.
 
I figured we could do with a general thread for certain matters pertaining the Royal Dutch Navy instead of having multiple smaller threads enter the void of obscurity.

Nice that article on your weblog dealing wit the Oerlikon rocket armament, I was 40 years ago responsible for describing the archive of the naval staff 1945-1948 and last decade for the naval drawings in the archive of Kon. Mij. De Schelde, I am pleased that somebody is using both archives.

Good news, the blueprints can be viewed online. Also I may have confused the company name. It was Yarrow not Thornycroft.

The second and third picture look like the same blueprint photographed under different lighting... no, they ARE exactly the same, save for writings in lower right corner. Or there are some subtle differences in blueprints that I fail to notice?

Otherwise, excellent find. Although the 950-ton one looks like something that should be offered to Netherlands in 1913-14, not in 1925, but well, who knows what they were thinking about back then...

Any other info on the 133mm gun? Is it really a Bofors proposal, or re-use of the British QF Mark I? or even a Wilton-Fijenoord design?
Any other info regarding the proposal itself? Armour, Engine, displacement etc?

Could these be prelimianries of the Admiralen class Destroyers? (Van Ghent and Van Galen subclass?)
The 950ton design armament of 4" guns. Are these to be of British origin or Bofors (105mm)? Same for the 3" AA?
 
The second and third picture look like the same blueprint photographed under different lighting... no, they ARE exactly the same, save for writings in lower right corner. Or there are some subtle differences in blueprints that I fail to notice?

They are slightly different.
The first 1.400ton design had 4x1 12cm, 1x1 76mm and 1 Seaplane
The second replaced the seaplane and AA gun to 3x 40mm 2-pdr AA guns and got shorter from 96meters to 94,5meters (from 315 to 310ft)
The 3rd seems to be the same?
But myself as well could not see a difference between the 2nd and 3rd designs

You are right, they're just both copies of the same blueprint. I just posted everything and since they're two different objects it went by me. I was already wondering why I had one more design than I remembered.
