that one is fairly simple
left knob is a minute timer you can either set to manual ( turn anti clock to the hand) or turn it right to the length of the cooking time
middle knob is the thermostat. you could buy an oven thermometer to find where the important places are
right knob is function
from what i can see going clockwise defrost, full grill, half grill
dont know the rest so you will have to experiment , open the door turn to manual and turn thermostat up. then turn knob anti clock wise and see if the oven fan turns on and heat comes out of the back of the oven. if yes you have found the main oven
if you find model, Should be round the door if not unscrew oven as i think its repeated on the frame , i may be able to find the manual
