In "The Women" (1939) the number called to 'John' in New York is ELdorado 5-3598.
As far as the phones used I just got done watching "Dallas" and they used a whole hodge-podge of different phones. Many WECO Princesses (touch tone) as well as an AE dial phone, WECO dial phones. Offices used WECO 2565 as well as call director type phones. They never had the "ringing" right and always used the double-gong ringers that one would find on 500/2500 type phones. When using payphones they'd have the "ding-ding" sound from a regular fortress type phone. The last "ding-ding" pay phones were the three slotters!
