Caswell Mack & Co. was the first to use this style bottle and they are harder to find than the more common Caswell Hazard examples. The clear bottle, shown on the left, is considered rare. The second bottle, the cobalt example, is the most common in the group. The third Mack shown is in a very deep violet color (the photo does not show the true color). Only a handful of these have been seen and those have been very crude in manufacture, especially in the area of the lip and neck.
