MikeW, I am an Ex Army Apprentice, I joined the AAS in 1952 and spent three years at Arborfield learning to be an Instrument Technician and also a soldier.
There was another schools at Chepstow
On completion of my three years I was a Class three Technician and was posted to various places around the world, Hong Kong, Kenya and Germany and some home postings.
Along the way I aquired 1st class status and served for 25 years.
I then retired from the army and took up with a world famous Swiss surveying equipment manufacture who I served with for 25 years.
I am now retired but still work on instruments.
Basic skills and machining were the order of the day and as you went from Unit to Unit your role changed so you had to be adaptable.
One place I am in optics another in electronics.
I had a good life and enjoyed where I was sent.
After 60 years I am still in touch with lads I went to Arborfield with.
