Pretty sure there were domestic models in black before the 'modern' ones - taller and with sharper edges and some proper braided cord for the handset. Our first phone was a modern one, but I'm sure I have seen the older ones in friends' houses. But it was a very long time ago now! I think I still retain the phone etiquette of the 60s - I won't phone anyone after 9 pm or before 8 am unless pre-arranged or life-and-death. Younger colleagues I work with sleep with their phones by the bed and expect to be/don't mind being called literally at any time. I couldn't live with that, so my phone stays in my work bag, which is well out of earshot of the bedroom.
300 type, black and rather heavy. Even the handset was heavy. Once the 700 type was brought out a special handset came out with a neon in the back that flashed when the phone was ringing. We had to fit one to an old phone, for someone hard of hearing, but it was too light to push down the cradle so had a metal weight inserted in the handle.
The 300 type had an integrated bell set, the earlier one, 200 type, had a separate bell set, like an extension bell, that screwed on the bottom.
I've got loads more useless information stored.
