I would think with a large skilled workforce like Vickers would have had eg many toolmakers , fitters and so on, it would have been a fairly quick project. Britain was arguably the leading land of engineering back then . The machine tools they had in the 1930's were pretty damn good . The Germans had invented carbide cutters and others were going ahead with experimenting with carbide cutters . I have an old catalogue of Churchill grinders somewhere, the size and different types of grinders they made is staggering.
Britain had so many machine tool makers it's beyond comprehension.
This is a good insight into it
