This appears to be a generic version of the Nettel, Contessa Nettel or Zeiss Tropical Sonnet.
The facade is slightly different from those models and there is no indication of the manufacturer.
The lens is a Hermagis Hellor 105mm f4.5.
This suggests that the camera may have been marketed by Hermagis as a vehicle for their lenses.
The right hand upright support has a crack in the metal, and the camera needs to be closed gently to avoid damaging it any more (visible in second picture).
