| The British Post Office’s CT725 “Renters’ Portable” coinbox was an innovative mobile version of the standard pay‑on‑answer payphone, introduced in the mid-1970s for use in places like pubs, restaurants, garages, hairdressers, and similar rented premises. Here’s what makes it noteworthy. The CT725 Renters’ Portable Coinbox (CCB 725A) was most likely manufactured by ATM (Automatic Telephone Manufacturing Company) or STC (Standard Telephones and Cables. A limited run of 250 units (40 in active trial plus 10 trolley-mounted) were deployed in the North East Telephone Region for feedback, geared at renters already using older CCB1/735D units. The trolleys allowed placement in customer-facing areas, such as hair salons or hospital reception, making the coinbox easy to move without wall mounting. Replaced the older fixed CCB1/735D, offering substantial weight savings and greater mobility . Early pay‑on‑answer renters’ units were fixed until the CT725 (CCB 725A) modernized that concept in the late 1960s and ’70s |
