LOL! Fish sounds good, with hot biscuits and coffee! I sense a smelt feed comin' on in the near future.
I agree that the B and C are essentially the same height. I just put the nose gear from a BN under what had been my wide-front Super C. But the center of gravity on the C/SC is a good bit higher than on the B. As and Bs alike, you had the mass of the final drives much closer to the ground moving the COG lower. On the C/SC, you have a much heavier transmission, diff and their housing behind that same axis as the center of the crank, and similar weight and length in the axle housings to the diff shaft housings of the B/BN. By moving the concentration of the mass up from the drop-drives to the same axis as the crank, you have raised the COG, and it will move to the tipping line much more quickly.
As for using the span of the front wheels to determine that line, I'd say that holds true within the range of the axial motion of the front pivot on a wide front when the weight is being carrtied to both wheels, but once that limit is reached, you lose your rectangle and are back to the triangle of a narrow front, and the apex at the front of the tractor moves to either the pivot point, or to any stops further out the radius, moving the tipping line to that point on the low side and much closer to the wheel, and transmitting the bulk of the weight on the front to that wheel. Jim N's drawing below, I'm still scratching my head, but he hits the point I'm trying to make. He draws the tipping line for a wide front to the center pivot point. Not sure if that's the true case or not, but even if it is, the wheels at the end of a wide front serve as outriggers.
So all of that was factored into the engineering of the chassis, and works on fairly regular ground even on a reasonable side slope and up to the point where you encounter the limit on the pivot point. But that's where operator judgment enters back into it.
I've rambled on enough. (How many times has this horse been whipped to death on these boards, but I still enjoy the discussion!)
Bottom line, yes, with all other factors the same, a wide front is geometrically more stable than a narrow front. But the finer point is that that does not make a narrow front inherently unstable and, I would argue further, that the offset of an A, or the shifting of the COG when a wide front hits the limits of the front pivot, pose just as much hazard and require just as much care in their operation as a narrow front. They can go over just as quickly as a NF which has a COG that is centered and does not move.
Now, I need to run to the store and see if I can still get fresh smelts. It's gettin' close to the end of the season, if it isn't already over.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
