Imperial pipe bigger than the norm

[supergas]

Hi Guys,
I know imperial pipes have been widely discussed on here but I haven't come across a suitable solution for this oversized imperial pipe.
I have come across much imperial pipes in my time and have always either got a regular 15mm fitting or an imperial to metric adaptor, the pipe i have come across today in a preists house is larger than anything I have come across previously, It's more like 17mm and I can't even get a 15mm pipe slice on. Im aware it could be 15 internal and have thick walls which add to the thickness. Im stumped so open to suggestions.


Has anyone got a solution to connect to this stuff?

Thanks in advance

Rich.

Any chance of getting 15mm inside it and soldering?
Maybe with a 15mm swaging tool.
