[Spridgets] Question about British Auto Association?

[Tim Collins]

The "Just a Car Guy" blog has pictues of a 1914 Boat Tail Rolls. See: 
http://justacarguy.blogspot.com/
One of the pictures is a badge consisting of a circle with two 
capital "A's" inside which overlap at the crossbar of the letters. Is 
this a badge for the British Auto Association? The badge is numbered 
on the bottom. There is a phone number and a telegram address on the 
circle part. How long this that kind of badge get used in England?
