Hello Bigaloscar
You are talking to an ex sparky, teleprinters, etc and all. Dont talk about it much as its a bit of a conversation killler normally plus signing the "old official secrets act kind of makes you not want to in case someone is hiding round the corner ready to haul you off to the glass house.
Had some good times doing "the job" in far flung odd places that I did not know existed until I landed where I was sent, so to speak.
One things for sure though there was no jobs going in Civvy street for an ex sparky. I had to re train in another field to be able to work.
