Ha ha. No, not yet (but have recorded it).
My Grandfather worked at Ryton in the 60s though, but only in the boiler room.
Slightly off topic. When I were nobbut a lad, the chap over the road won a Minx derivative (can't recall which one) in a CET competition. About two years later me and my mates were hoofing a football around the street and it hit the car low down on a door. The shower of rust that fell from the sill was quite shocking.
Terrible old sheds.
