Great 105, when was it made? Is the protruding knob/handle a simmer control? Mine is a later model so, some of these details are new to me. Thanks for the photos....
I have not seen a 105 Sport before - in fact I can not find it in the CCS published literature. Is the regulated silent burner original? If so, then you have a quite rare stove. Ross may have other unpublished literature which will shed light on this stove. Anyway . . . . . what a great find!!
