#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!
