Well I haven't a bloody clue, just been through Laidlers "Identification of Buttstock Marking Discs in British service 1900 - 1944" and it hasn't helped me.
He doesn't list Ardrossan Academy, bloody wet place Ardrossan, in the officers training schools list, but so what I hear you say.
I reckon its for the Alcholics Anonymous Batalion myself.
I hate buttstock disc questions, they do my head in, I don't think I've ever found a disc thats been on any of the lists as shown. <!--EZCODE EMOTICON START >: --><img src=
