Hi, glad to help Tony!
Hans Heesakkers posted the contents of the Dutch contract with AAC on these guns on the thread about the mystery guns:

"25 september 1940 the Royal Dutch Navy ordered 40 37 mm guns and 80.000 rouns ammo. Costprice $848.000,=.
The guns were called "3,7 cm Semi Automatic Anti-Aircraft Gun on Naval Pedestal Mounts". All guns reached Java in time (the last approx June 1941). The guns were produced in the Rahway factory and the ammo in the Derry factory. Most if not all the guns survived the war and were re used during 1945-1950 as the main armament of the "R.P." (Regionale Patrouille)-boats."
I have also seen a picture of an AAC 37mm gun on an Dutch LST during landing operations on Java in the 1945-50 period.
They were L50 btw.
I took a series of picture of the real thing at Den Helder Navy Museum Depot, so if you'll need one of theose, let me know.
Good that you want to be conprehensive! Finally we have a chance of seeing the Dutch naval guns in good order.
Do you need info on the HIH Siderius naval guns and there data? I can compile a list for you, if you want.
Cheers,
Nuyt
