As everyone knows Britain's wartime Prime Minister Winston Churchill was a former soldier and loved to "test" all kinds of new weaponry.
After test-firing a Thompson Sub-Machine Gun on a rifle range early in the war Winston declared it was a "real war-winner".
On hearing this in America, Franklin Delano Roosevelt had a special Thompson made for the P.M. and presented it to him at the Casablanca Conference.
Our Churchill is based on a famous photograph taken during the war.
