a lot of W123 and also a lot of old BMW sedans were like that - power windows in the front only, I have also seen a W123 with power windows in the back only, I think that was a taxi convert but cannot prove it.

The 200 and 230 was a very common car for W123, the cloth interior and simplicity speaks of MB quality.
