Technically, this is a Vickers Machine Gunners Slide Rule. But works on the same general "vernier" slide principle as a Mil Dot Master.
Designed to help set inclination, declination, deflection, wind, dropping rounds BLOS, etc. It's graduated out to 2800 yards, from what I can determine. And you thought firing a machine gun was easy...
This unit is WWII Australian. Would be for .303 Ball. It would not surprise me if the ballistics were pretty close for Enfields.
Just a neat thing I picked up and thought people might like to see.
Cheers,
