This has probably been mentioned before, but in case some of you are unaware that YouTube.com has a tremendous amount of AFV associated film clips. In just a few minutes I found vintage clips of German trials comparing the Panther the Lee, a clip of a restored JagdPanther actually firing its gun, German propaganda films showing various vehicles, a film of them starting the King Tiger at Samur. Plus they have film footage of the 3rd AD moving into Cologne, which includes a Pershing going toe to toe with a Panther.

If you haven't discovered YouTube yet take a moment to go look!
