Those are two different tenders - one scratch, the other MG. Also a note on boiler tapers: My ATSF Steam book shows most Mikes, Mountains, and 2-10-2s with considerably more boiler taper. I found photos of each type showing very slight tapers, so I am getting away with these models. That's my story, and I am sticking with it.
I guess that is not so unusual - I am convinced that the PRR used two different tapers on the M1 Mountains. When I do my M1, it will be with the more pleasing and gradual early taper, and an eight axle tender.
