Friends ambulance unit China badge

[magu]

Hello Folks
Picked this badge up last year ,in the early morning gloom i thought it was a festival of Britain badge until i got home and looked a little more closely.
Its actually an individually numbered F.A.U badge from the contingent sent to China in 1941.

Book on the China convoy http://www.sacu.org/fau.html

Does anyone have a copy of the book to hand (its on my 'to get' list) and would it be possible to check if the badge number corresponds to any individual listed in a roll of personnel in the book (if it exists in the book that is )
