I truly am not sure what this was used for but the two bottles are very old and the hand crafted leather case was specifically made for these two bottles. The initial "J D " have been tooled into the leather. Overall size of bottles is 8 ¾" in length and are 2 ½" in width with a depth of 1". The case can be worn on a belt. Each bottle has a screw cap and then a safety piece that fits over the screw cap. Check out the pictures. One of the caps has a crack and the whole set could be cleaned up but I like the patina and will let the next owner do what they will with the set. The bottles are concaved on one side.
