Description

#749     CD 110.5     NAT. INSUL. CO.      (Four patent dates) on base.      Blue aqua.

Two segmented threading.

The small size "corkscrew" insulator.  An abundance of base embossing is executed in a very detailed, precise manner. Most examples of the CD 110.5 now in collections were recovered along the route of an AT&T long distance telephone line between New York and Philadelphia.

Perfect embossing.  A damage prone style that's extremely tough to find in this very, very near mint condition!
