I thought you might appreciate the above pictured, stunning `Recruiting Poster` that ex A/T Charles Train (56B) dreamt up for the A.O.H.A in April 2001!!  As Charles says:  "It shows the badges of the different branches of the Army that Harrogate Apprentices transferred to in the 1950s and early 1960s once they had completed their three years at the Apprentices School.  This was prior to A.A.S. Harrogate becoming predominately a Royal Signals Training College."
