Hemingray Insulator Profile: CD 122  
This common toll style replaced the earlier No.16 style (CD 121) in the 1920's. These were produced in mass quantities, so most are very common. Aqua, Hemingray Blue, and Ice Blue pieces were manufactured until c.1938. Afterwards, all CD 122's produced were clear or straw.

Small Wire Groove Variant

Later versions with the small stamped style embossing came in two different wire groove sizes, hence the No.17 style number. The new No.17's took on the attributes of the old No.16 (shown above), while the new No.16 was given a smaller wire groove (shown at left). See this image for exact dimensions taken directly from a 1956 Hemingray catalog.
