This is a very nice item in excellent condition. The Adjustable head is made of Brass while the handle has been made from a hard 'turned' wood. The cup opens for One, One and a Quarter to One and a Half ounces of shot. Alternatively you can measure gunpowder from Two and a Half to Three and a Half Drams with other fractions inbetween.There are 16 drams to an ounce. The Brass Head will polish up nicely.
