Much appreciated.

It all gets a bit vague with Eighties parts and £30 is a lot to pay in a trial-and-error scenario.

Shimano UN55 is available ITA 115mm and £15-odd: for the sake of 1.5mm on each side, I'd be tempted to give that a whirl.

Or just get another set of cranks...

I have a feeling it’s ISO. I think on the SR 80s cranks, 130 bcd was JIS, and 144 was ISO. Will give it a try on my SR bb which is ISO, first.
