Well found Toni!! Yep, that's the one
I have some scans of old catalogues, and as well as coming in sets, playpeople doctors and nurses were also sold as individual figures..(this leaflet was from 1976)
and in a variety of sizes of sets.
It seems that set number 1740 may be the one. Playpeople were where my Playmobil obsession started - it's got gradually worse since then! lol
