I am sure that the manufacturer of Motor Sich But I do not know the name of the model. Some elements are repeated in OIP-2C. But the principle is that of the IFN "Everest", "Ray". But components such as a pump, a fuel tank, and a knob regulator are characteristic of the Motor Sich. I think that the name of the model should be "OIP-1" or "OIP-2" without the letter "C". If someone knows something about this oven please write.
