So what particular model is it? From what year? Any other details you know?
The bike was manufactured by BSA, the chainring is an obvious clue, it's also a "ladies" model (parallel top tube). Looks very similar this 1975 BSA Wayfarer. The linked post has a lot of detailed photos you can compare the frame to. Pay attention to chainring with BSA letters, arrows on chormed fork crown, rear dropouts and dropout eyelets, tube taper at seatstay/seatpost junction.
Here's how I went with search: "lettered chainring", "sprocket with letters", "bsa retro bicycle ladies", "bsa bikes retro catalog", "1970 bsa wayfarer".
