| Further notes |
| Overview & Function The KS-19426 serves as a mounting structure for 2A-type coin-operated telephones, explicitly designed for walk-up installations, It is detailed in Bell System Practices Section 508-470-100, Issue 3 (August 1965) under the title “Walk-Up, Drive-Up Public Telephones – KS-19426 Mounting”, which covers identification and assembly of the mounting Additional context appears in coin telephone installation manuals, which reference KS-19426 alongside other booth types (like KS-19340, KS-19206, and KS-19442), showing that KS-19426 is one of several mounting options depending on environment Manufacturer Manufacturer details are not explicitly stated in the available Bell System documentation for the KS-19426 mounting. However, in that era, Western Electric was the Bell System’s equipment branding and distribution arm. The actual physical components—especially enclosures and booth structures—were often produced by contractors like Alcoa (Aluminum Company of America) (as with the KS-16797 and similar models). Given the material and function, it’s plausible that Alcoa or a similar third-party contractor fabricated the KS-19426 mounting, though no direct attribution is documented. |
