40 mm Bofors AA guns made in GB and US

[Stellan Bojerud (RIP)]

Thank you John for these interesting pictures!

I have found some new information regarding the British Bofors production.

In 1939 the production was made by "one of the Royal Ordnance Factories" (which?) and the Nuffield Group. In 1940 six companies were organised as the "40 mm Mounting Group" which was chaired by Artur Stephens.

In June 1940 A. Reyrolle & Co Ltd got a contract for producing Bofors-gunmounts. This was however soon changed to the full assembly of the guns.

Guns and carriages were not made by Reyrolle but supplied from other factories. The production line took considerable time to set up and reached capacity by late 1941.

The production made by Reyrolle ceased in December 1943. By then Reyrolle had produced 1.580 Bofors guns.

Reyrolle also made "Kerrison Predictors" - unknown number.
