1) Les annales de la guerre No 64 - it's film with Elfriede. A7V is from 2:39 to 3:20. First part (driving) is better known one (I saw it on f.e. youtube), but second one (posing to well known photo ;) ) starting at 3:13 is rather ommited.
(unfortunatelly I can't give direct link to film, because it's rtmp stream, but it is possible to download it with some tools, file is quite small, about 6MB).
3) Canadians Advance East of Arras (3) - short fragment (7:35-8:10) with Hagen
contains plenty of films with various tanks, especially theese two are quite interesting:
- The Royal Visit to the Battlefields of France, July 1917 (1) - we can see, that 2 things every officer during WWI must have is stick and dog . Seriously - nice stuff starts about 5 minute - tankodrome and downhill ride from ~10m obstacle...
I hope not all films everybody knows - I'm sorry for littering if I'm wrong. I'm looking for other films, I know about c.a. 5 other, but it's hard to find them - when I'll succeed I'll give links.
