The rear GMC diesel engine produced about 150hp and drove the track over 3 top idlers, around the front idler and back via 2 distinctive 3 wheel bogies. The turret had power traverse with a 6pdr A/T gun. The armour was good for this size of vehicle. The Valentine IX was the up gunned Valentine V which had a larger turret to accomodate a extra crew member, and had the GMC engine.

The subsequent Mk IV was fitted with an L/50 barrel, with muzzle brake.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
