100S Spec Question

[MikeAH100M]

David Ley, a friend of mine and a very talented restorer, is converting a rusted out, barn find BN2 into an all alloy-bodied racer with LeMans mods and 4 wheel disc brakes (pictured here with my 100M at the Pittsburgh Vintage Grand Prix this weekend). Also doing 100S seats and fuel cap. Since the car has 4 wheel disc brakes, he asked me where he could find out what the master cylinder bore was on a 100S. Anyone know where we could find that info?
PS: the car will eventually be for sale. Engine is just being finished

There's a 100S group on Facebook. Might try asking there: https://www.facebook.com/groups/304536206395420/

The master cylinder is Dunlop VB300. it is iron, 1 3/8 stroke 7/8 bore per the title block on the drawing. Good luck.
