This camera is similar to the model shown above but probably older.

The differences between the two models :
- there are 2 bubble-levels on this one
- the Color-Black lever on bottom misses.
- lenses are Darlot Foy Planigraphe 81mm # 2518 and 2519.

Curiously, the magazine backs are of slightly different size and so, can not be interchanged between the two cameras.
