Anyone know any of the above?  I certainly recall Captain 'Alfie' Alfred RSignals, ex SSM at AAS Harrogate.  (He's the one behind the dog!)  Note too the SAS Sgt to the left of the picture:  I doubt if that cap badge was ever worn on later courses.

Photograph taken on Helles Barrack Square:  I know 'cos I was lurking around at that time in my last few weeks as 11th Signal Regiment Post NCO!
