#007 Triumph TRW “The ressurection”
The Triumph TRW was designed in 1943, but by the time the bike was finished, the war was over and the military had a surplus of bikes left over. In 1948 the TRW was released in it’s final form and were sold to the British Army as well as other branches of the military, at home and abroad. This continued until the 1960s.
