Not sure this model. It's the same as the 1200 model, but the color of fuel tank and generator is different.
It's a 1200 series for sure but some PO has stripped the nickel plate to leave it in brass. If the top casting has a brass plug with a 1/8" hole then it's model 1225 and a Q99 type generator will fit and work. If there is a large hole then model 1200 but finding a generator with its pricker mechanism will be near impossble. ::Neil::
This is a 1200 generator which has a quite wide head. And this is the brass plug in the burner for 1225. ::Neil::
