TELEPHONES 237AW & 237CBW
HANDSET TYPE WALL TELEPHONE RECONSTRUCTED, AUTO AND CB

Telephone 237AW and Telephone 237CBW are handset types converted from a wooden CB bell box.  The serial numbers are 1/22 and 1/21.

Drawing C.l5l4 shows the wiring of both the CB and Automatic telephone and a copy is fixed inside the instrument.  The CB instrument is not convertible to automatic and will be changed if the service is to become automatic.  Experience has shown that the instruments in `convertible' form is not always warranted and many are never converted. In the present case, the plain front is being retained.

This telephone has all the advantages in quality and volume of transmission and reception provided in the latest types of handset instruments.

When stocks are available these instruments will be issued for all wall type handsets in CB and automatic areas.  The use of table telephones mounted on brackets (162AT/CBT, 232AT/CBT and 332AT/CBT on brackets) will be discontinued as soon as possible.
