These come in several different inner and outer skirt variants. This particular piece is one of the taller specimens, with an extended inner skirt that makes it about 3/8" taller than the average CD 1049. These seem to be less common.

No Name and No Embossing variants have been found with rounded wire grooves (compare to the square wire grooves of the Owens-Illinois embossed pieces). At this time, it is unknown if Hemingray manufactured these pieces.
