I am going to suggest that John took the casting, separated the cab, reduced the "Lowey" angle (you can see less space between the cab bulkhead and that first screen), and lopped off a quarter inch of the rear cab, re-locating the bulkhead to reduce the width of that hideous window. It appears he re-did the window, which is a really great idea, for both this and the H16-44 of the same lineage.
If you study the photos immediately above, you can see where the cab bulkhead intercepts the truck sideframe, if you drop an imaginary line from various places on the slant bulkhead.
So we may attempt something like that - I am proposing a straight-side cab, no Loewy slant, and no Loewy window - the decision as to whether the back of the cab has rounded edges or not remains for later.
Wheelbases are somewhat nebulous - the H10-44 and H12-44 have 25.5 foot between centers, and we are not sure yet what the H20-44 is. Truck sideframes might also be problematic, but our secret weapon is Stevenson, who has always been willing to make a few castings for us.
The really nice Kemtron RS truck is 9'3" wheelbase. I have some sand castings with roller bearing caps that scale out to closer to 9'7". One Fairbanks Morse drawing shows an 8' wheelbase, but the drawing shows the EMD switcher truck, as used on the SP. So it appears that we can do what we want and still remain more or less faithful to the prototype - which may wind up being green, red, and yellow P&WV.
