"Bruce Barrymore Halpenny-British military historian and Author, served Royal Air Force Police"
There seems to be some doubt as to the validity of this gentleman's duties - now I'm not going as far as to suggest 'Walting', but his own descriptions of what he did as a National Serviceman and after seem to be a little 'embellished'?
I may be wrong, and apologise profusely if I am, but if anyone has any further information I would be most interested.
