I just saw this, and thought i would share it here (not sure which category it goes to) here is the caption for it..
"A German repair shop for captured British tanks. During the Battle of Arras, the Germans had captured their first tank, it was brought to one of these shops to study and analyse. Later on the Germans captured even more tanks and actually deployed them again. These "Beutepanzer" were rearmed with German machine guns and overall more were fielded than German built A7Vs."
