Thanks for the heads up. Just watched the video and the scenes at the BSA factory were very interesting as was the different approach in those days to Health & Safety with what I assume were BSA test riders!
However, the part of the video I wasn't convinced about was the shots of Smallbrook Queensway in the centre of Birmingham showing it 75% completed. I am pretty sure the redevelopment of Birmingham city centre didn't begin until the mid-1950's with the Queensway not being completed in 1961?
