Just started reading your blog fishyfish - I started work in Sheffield in Sept 1965 and spent 8 years working mainly on steel company audits, then I moved to Doncaster to work for British Ropes, (Bridon), for another 8 years - wish I'd taken lots of shots especially inside the steel works as I realise now how interesting they would have been.
Thanks for your comment on the Hovercraft image - or Hoovercraft as a friend's mother used to call them!!
Remind you of your first blog post
but with the metal shutter button - I bought it in 1973 and still have it
