As part of their releases for Flames of War The Great War, Battlefront have released a 15mm scale Whippet tank.
Though originally envisioned with a rotating turret, the production model had an armoured housing for three to four 303 Hotchkiss machine guns, which could be relocated between four gun ports. Approved in June 1917, roughly 200 vehicles were produced starting in October 1917.
Unlike the large crew of the Mark IV, the Whippet managed with a standard crew of three: a commander, driver and gunner. Given the gunner was responsible for manning both machineguns (which could point forward, left, right and rear), sometimes a second gunner was squeezed in.
It looks like a very nice model and well sculptured. Lots of detail and a good casting.
I do think that this model would make for a great base for vehicles for an alternative Great War. It could be converted into a turreted tank, or a self propelled gun. One other idea is to use the models for A Very British Civil War background. There are quite a few models in the Flames of War range that could be used for a 1920s or 1930s civil war within the United Kingdom.
