Glass is 2-3/4 inches tall and holds 2 oz. Optic and color treatment look like Morgantown's "Fire and Ice" pattern made for institutional customers.
The McCann's have one that is 3-3/8 inches tall and holds 5 oz which matches except that it does not have the etched or cut line near the top. The line is at what would be the 1 oz level. Perhaps, it was marked to allow a bartender to use it for either a single or a double shot.
