Do you have any further information about the tank and location?
Sorry, Sniper, I don't. The post card was along with a group of artillery photos I purchased. There is nothing on the back except typed in English: "A German tank going across the trenches." Tanks aren't really my thing, everything I know I learned from Landships... so there's nothing I can add...
The second Abt. 13 Mk.IV male, Wagen 209, had the Iron Crosses sitting lower - and they were not so nicely curved. 209 was Number 4; 213 was Number 5. - The viewer (photographer) is in the trench system on the hilltop, the tank comes climbing up from the valley below. The Abt. 13 exercises done at Lieu St. Amand are well documented in the detachment's war diary - and quite some pictures showing the tanks have survived.
