Chuck retaining screw?

What size is a left hand retaining screw for Macalister 600 electric drill. M4 M5 or M6
Jim reilly, July 2017
probably 5mm. What size is the hole in the chuck? Slide the back ends of various drill bits down till you find the size which is too big and work down

This may be useful. Lots of diagrams
