There is a picture of tanks in India from 1938

Mechanization reached India in 1938. Duncan Crow has a picture showing a troop leader's Lt.Mk.VI between two Lt.Mk.IIB's, plus a Lt.Mk.VI next to an Indian Pattern Lt.Mk.IIB. This was the 17th/21st Lancers. The other two regiments in the brigade were the 15th Lancers and the famous Central Indian Horse (otherwise known as the 21st King George's Own Horse). The Lt.Mk.IIB's were tiny vehicles, even next to a Lt.Mk.VI, which was none too large, itself.
