A side note: the standard Western Electric telephone had a REN of 1. RBOCS, knowing how many telephones each address was paying for, could test the impedance of a telephone line and determine if the correct number of telephones were connected. If there was a discrepancy, Ma Bell would pay an unannounced visit to check things out.

My dad leased 1 telephone from New England Telephone. The prior owner of the house left a vintage 1957 C/D 500 behind (not sure how that happened back in 1967) in the master bedroom. New England Telephone wired the extension, so the company should have had it documented. My dad removed the ringer assembly and kept the phone. We still have the phone. My dad switched the cord from a four prong to modular. I installed a new ringer several years ago. The handset is amplified and has the thumb wheel.
