From James Webber:
I’ve found nothing on Graham Roch [pronounced ‘rock’] who was a lieutenant at the time: do you know about him? 
About the Gunners 1962-1964: I would like to know who the Gunners were: there must be some record of the Gunners by name, & the Gun-crew of each gun: do you know where I can find the records?  Most of the Gunners had completed their Basic Training Call-Up & were completing their 3-years Military Service: there were a few like myself who had just volunteered.
Thanks for any assistance you can give.
