Like Lt. Ripley said on Aliens, "I'll tell you what I know". This is my best educated guess given the photos.
With Lotus it seems there is a lot of conjecture.
Solid Seat tube decal and painted head tube is post 1981.
Crank may not be original, pedals definitely not. Yet the chain ring looks drilled for a guard.
Steel head set is a lower-end bike. Under a Classique.
It doesn't have Shimano 600 Brakes so that rules out the Eclair.
I'm guessing an Excelle or Unique given that those two bikes came in black and used Dia Compe Brakes instead of Shimano 600 to match the derailleurs. The crank is hard to see in the photos. Without original saddle, pedals or crank identification, that's all I know.
