Hi all,

Can somebody identify these equipments ?
Especially, I am interested in the device to the right of the picture...and in the origin of the rangefinder in the centre...

What you have there is a very early, and simple, set of AA fire controls. The item on the left gives elevation and bearing inputs to the target. The rangefinder, gives the range. The device on the right is a lead computer. The operator dials in the bearings, elevation, and range. It mechanically solves the time, speed, distance equation to calculate the required lead on the target. The output is fed by telephone or sound powered phones to the guns.

Thank you very much for your help, T. A. Gardner. Do you know which is the manufacturer of this set specifically ?

Sorry, no idea off hand. Maybe someone could ID the rangefinder and that would give some idea as to the rest of the gear. Knowing the year of the photo and what battery it was used with would help too. It has to be pre WW 2 as the electro-mechanical sets became common by the late 30's.

Re #83 Post 26 Dec 2018, 22:40 My records list this as a "Berkog with attached 3 meter range/height finder. Primarily associated with the 105 mm AA Gun M1931 Bofors L44 of which 4 were in the KNIL.

It looks like a 6 meter rangefinder for the 10.5cm SK c/32 as with Battery Vlieland West shown in the link
