I didn't work at Elastic Yarns myself - well apart from a few weeks during school holidays occasionally! , but my Dad, Ted Hurst, worked there for many years. I wonder if you remember him? I'm in touch with an old work colleague of my Dad's - Alan Rose. Do you remember him too?
As for NAAFI, my brother Michael Hurst (Mike or Mick), worked there in the 60's.
Hope you remember my family!
