Green Glass Ashtray

I am not sure of the manufacturer of this vintage ashtray. It is made in such a manner as to accommodate a cigarette or cigar. It measures approximately 5 1/2 inches. I photographed it in direct sunlight to show a slight imperfection in the glass on the underside, but it is so slight as to not show up. It is smooth on both sides of the area and does not appear as damage. One area of roughness on the exterior mold line. Additional photos by email. I need your zip code to calculate the postage.
