It is generally stated that the armour increased from 7.25mm to 8.25mm, but my Mark 1 demonstrates that this thickness was already in use. The only difference when compared to the Mark 1 seems to be an increase in engine power to 72 bhp at 4000 rpm. Rather confusingly I have a Mark 1 sales brochure that states the engine power was already 72 bhp! Production figure was about 50.

Shorland Mark 2 as it appears on the sales brochure. This image is actually reversed, although the unmodified image was used on early brochures for the Mark 3.
