40 mm Bofors AA guns made in GB and US

[Stellan Bojerud (RIP)]

I have come across information that 40 mm Bofors guns were also made by Waygood Otis Ltd in GB.

Where was this Factory located?

I also learnt that Otis Fensom Elevator did not have a factory in Vancouver. But the question about Dominion Bridge does so far have no answer.

Re Tony´s picture. It was SOP to remove the sights from the gun before travelling.
