40 mm Bofors AA guns made in GB and US

[Stellan Bojerud (RIP)]

What happened was that the firing units had two trucks.

One with a 40 mm gun. Driver + 3 detachment (crew) + 120 rounds.

Another truck with the Kerrison Predictor. Driver + 2 men + 192 rounds.

The gun truck could fire with "open sights". (Gunlayer right = traverse, gunlayer left = elevation plus trigger with foot pedal).

To use the Predictor both trucks had to stop and an electric cable attached between them.

The British MK III Bofors and the Canadian MK 1 C are Chinese copies and I cannot on a photo distinguish one from the other. Must read the brass plate or marks stamped into the breech.
