1886 Shooting oz dram Gun Powder and Shot Measure Adjustable BGI

This adjustable powder and shot measure is marked on the bottom "B.G.I. Co. Pat. Nov 23 86" and is marked in drams and ounces on opposite sides of the cup. Inside the cup is some rust and corrosion, but it slides up and down without any difficulty. The handle appears to be walnut. This is an early example of this shooting measure and it will be a nice addition to your collection.
