Found this in my shed, Think its an isolating valve off the air analysis system, used to turn off the gas in the back of an old ex BT optic cable line van I used to have.
recon it would look like a load on its way to a water/ sewage pumping station, modern type, any experts on here like to comment??
EDIT:- Strange forum would not let me add pic to post, box came up blank white no text, looks like it might work now as an edit
