Description

#750     CD 110.5     NAT. INSULATOR CO.      (Four patent dates) on base.      Green tinted aqua.

The "corkscrew" insulator is quite unusual!  The spiral "corkscrew" top was was designed to accept a horseshoe shaped clip, which eliminated the need for a tie wire.

The vast majority of examples found to date are a distinctive blue tone.  Examples such as this, with greenish tint, are much scarcer.

Perfect embossing.  Exceptional, very near mint+ condition!
