even if some of the figures are only estimates, or 'educated guesses'. The video also includes images of British matériel in German use, many of which I've not personally seen before. Some pics might inspire,or assist, a build here and there. 
No wonder it took us so long to make good the losses although, by 1943, Britain was actually out-manufacturing Germany by a considerable measure, in many spheres (aircraft, tanks, etc..)
Thanks, Louis.
