Here's an actual H8:

I still think the firebox and lower cab edge need to go way lower. I'm looking at the size of the lower firebox protrusion,
not just how far down it goes. It looks much much smaller on the model shell than the prototype.
Tony, you may be right that in the photos, the shell wasn't sitting all the way down on the model. But that doesn't make sense to me.
I would have thought one would want it to look its best if it's being shown in an ad to sell it.
I really am not trying to bash here, although I'm afraid it keeps sounding like it.
Since this thing is 3D printed, it would be a matter of correcting a CAD drawing and
getting an updated shell. Now is the time to correct these things so that the finished product turns out better.
