Ben makes a point about the roof and although it's freelanced, I'm not sure they ever put the handle on that side of the door. Possibly two handles might work, though. (In logging, they might have used a flat roof...)
You might want to extend the break wheel a bit higher, waist high is usually good. It looks about knee high, now.
Looks good, real good...
@ Ben, that Kiso #6 would be one fine addition to this hobby. Very unique to this game.
