40 mm Bofors AA guns made in GB and US

[Stellan Bojerud (RIP)]

1. The Kerrison Predictor owned by Tony Smith was made by
M & P. Ltd. - sounds as a British factory. But wich? To make this sofisticated mechanical computer a highly specialized factory is needed.

2. By coincidense I met an old friend in my favourite pub yesterday. He is an ex-RAF Officer. He told me that his father had been involved in making Bofors guns during WW 2. The factory was:

A.Reyrolle & Co. Ltd. Hebburn - on - Tyne, County Durham.

3. I have found out a few things regarding Otis-guns in Canada. The factory was ready 1st March 1941. The first gun test fired 10th Nov 1941. By Mrs 1943 the production rate in Hamilton (Ont) was 350 guns/month. Totally approx 5.000 guns made.

But - - - the number series shows that more than 20.000 guns were made 1942 - 43. So there must have been more factories involved.

Did Otis Fensome operate a gun factory in Vancouver? Did Dominion Bridge in Vancouver make Bofors guns?

I would be very thankful for help solving these questions.
