Victorian copper pipe size

[Peter]

I need to replace a corroded stopcock in a Victorian terrace. The problem is - I can't find a fitting for the original pipework. It is copper, and appears to be Imperial 3/4 inch. But - having cut a section out - I cannot find a compression fitting that will fit it.

It seems to be much thicker than modern copper pipe. And four local plumbing shops say they've never seen it before.

Does anyone know a source of some kind of adjustable compression fitting that will adapt from a weird 3/4-ish size down to modern metric?

There's some urgency to this - I've no water till it's done?

If nothing else will do it then look at the Universal Transition Fittings such as order code 13544 on
