Come across this today ? Cylinder

[Oftec robbie]

hi
Thanks for taking time to reading this
I’ve not come across a cylinder like this before
Oil boiler ,indirect cylinder works find but what’s going on up top please
Also there’s a bathroom radiator on the hot water side which is fine I understand that
Hope you can shed some light thanks

Looks like a prv at the back coming in but I’ve never seen a expansion vessel on a older cylinder
Early unvented ?
All the best

Not the best pic Sorry

Yes its an old unvented , early internal expansion, but its been converted to an external vessel .
Guessing at a Mk 2 Tribune .
Do not touch it unless you are G3

If you want to replace that cylinder in the future, I would happily take the old cylinder. Nice weight in copper.

Hmm. I spoke to the BBA some while ago. A guy who was orig committee setting up UVCs in 1985. He told me that no copper cylinder was BBA approved as they were too weak.
Could this therefore be someone's attempt at creating one? Ive certainly seen that - a block of flats in Harrogate where all the cylinders were std Jewsons withsome cont attached. Henxh contact with BBA. Just a thought.
