Megrez 72 Finder Shoe Tapped Hole Thread Size?!

[robbymain]

Hello you helpful bunch

Might anyone know what size of screw fits the single finder shoe tapped hole on a WO Megrez 72?

Just picked up a used one on here and want to have it ready and working in time for my Christmas holidays during which I will be very near Dartmoor during the new moon 😃

All the best,

Rob
