Is this 1" or 1 1/8" bore... my eyes suck!

Swapping out my master cylinder and putting in a disc/drum prop valve from a PO cluster bang and can't figure out the bore size of the MC. Where do you measure from? the lip, rubber surround... The sizes are so close I am getting nervous picking a size and ordering one. Any thoughts?

Appreciate the time!
