I’ve got a couple of Cornelius / Redditch Controls secondary regulators and want to add the pressure gauges. Anyone know what thread they are?

I would guess at 1/4” BSP.

They are certainly BSP. I can't quite recall whether 1/4"BSP or 1/8"BSP but like Lee I seem to think the former. You can check by measuring anyway - if they're 1/4"BSP then the threads will be about 11.5mm inside diameter (or 13mm outside diameter).
