NATIONAL TELEPHONE COMPANY
Pattern No. B19
NATIONAL TELEPHONE COMPANY'S STANDARD PATTERN
This type of instrument, of original design, and best quality, has, after long trial, been adopted by the Company as the most desirable form of wall set for use, not only on its ordinary exchange system, but on private lines. It contains the very latest improvements with most substantial construction, and has a neat, and pleasing appearance.
It should be specially noted that instruments very similar in form are offered by various makers, but such instruments cannot be compared with those sold by the Company.
Taken from the 1903 Catalogue.
