Anyone know the piston bore of a stock 550 Master Cylinder?

Does anyone know the bore diameter of a stock 550 brake master cylinder?  This would be essentially the same as the piston or seal diameter.  I'm not looking for the banjo bolt diameter.

The size on a lot of master cylinders is cast into the bottom of them.
