Dave,
I was a very newly-commissioned 20-year old 2/Lt when I met your Grandad, Ronald Hornby, as the Sqn Sgt Maj of 1 Sqn, 25 Signal Regt, in Ripon in November 1959. Despite his somewhat gruff exterior I discovered that he was a really nice guy and, together with Major Harry Rae, the Squadron OC, he managed to keep me on more or less the right path in my first few months in the Corps. When 25 Signal Regt was moved to Catterick in June(?) 1960 and became 1 Sqn of 24 Sig Regt, both he and Major Rae were posted elsewhere and I lost touch, although I believe he took a commission later in his career.
