the Company is Avon. Standard was just supplying the Chassis. you can read that in the Stanard article:

en.wikipedia.org/wiki/Standard_Motor_Company

if you dont trust wikipedia here is also a website confirming that those cars where called Avon Standard and not Standard Avon.

can someone change that?
