Gents, I don't want to stick my nose in here but I went through oasc biggin hill with a merchant navy navigation officer back in the mid 1980's. I'm probably way off beam here but it was he a big good looking blonde haired lad by any chance? I was looking at photo's of the lads at oasc just the other day! Alas.........I wasn't successful!
Sorry if I'm out of step here, but I just wondered?
