I've only ever seen similar on American cylinders - too youngnot seen any of the top covers for at least 50 years though

Used a few of them on my early days on GPO/BT keeping pressure up on main cables! They get a bit heavy dropping them down a manhole shaft on a rope.Hi, When I was delivering for BOC in '87 the only round bottom ones were air going into BT. Yes they were a pain, if we were lucky they would have a pallet load at a time.
