Old Gas Bottle
Ignore the Taz Bloke, if you have a spare I would appretiate one as it is well worth reading and as a reference document. I was surprised just how much of the worlds engineering development can be linked back to J & E Hall, had any of you out there wondered who invented the ventilators we see every day on buses and airplanes you know the round ball shaped ones, that would be J & E Hall then, and lots of other everyday items.
