the Mark IV tank named ' Scotch & Soda ' along with it's crew.

Posed photographs of an identified named WW1 Tank along with it's actual crew are quite rare, and what makes this particular tank and crew photograph so much more interesting is the crew's headwear, as each crew member appears to be wearing a Glengarry.

This might be indicative of the crew all being Scottish, or that because the tank was named Scotch and Soda, they may have dressed the part.
