Clutch master cylinder bore?

[Brummmie]

Looks like my clutch master cylinder is on the way, does anyone know the bore?

I would like to put an external res on, as that silly faired in one is a pain.

The Master Cylinder, assuming that it’s original, will have a number cast into ist reservoir external wall – such as "GIRLING70" – This indicates a bore of 0.7”.
