Conversation Tubes

Double Bell Small Metal Conversation Tube

This small conversation tube with metal bells has no maker's markings.

It likely dates to around 1920 or maybe earlier.

Since it was so small and flexible, it was easy to carry in a pocket or purse ready for use when needed.

The overall length of this conversation tube including both bells is 39˝" (100.3 cm). It weighs just 4.6 oz. (130 g).

The outside diameter of this small conversation tube is a hair under ˝" (1.2 cm) which is smaller than most conversation tubes. The tube diameter is constant throughout, whereas regular conversation tubes often were tapered.

This conversation tube was donated to the Hearing Aid Museum by Lynne Ranieri of Short Hills, NJ. Thanks Lynne.
