This is my N&W Hi Hood C-425 Phase III Project. The unit is an ATLAS Phase I with a Stewart C-630 Hi Hood and Cab (at 15 dollars for the 630 shell, this is the most expensive hi hood I’ve purchased to date). This modification was a little more involved than I thought it would be because the Stewart hood sits a little lower than the ATLAS does. I had to build up the bottom of the cab a bit with plastic. The cab steps are from an ATLAS Canadian Cab C-424 as is the fuel tank. I still have to make the battery boxes that go under the walkway.
Excellent! And no masking required to paint the unit!
Just a slight pedantic nit – I think the three-width stepped radiator housing and snow shields over the central air intakes qualify the prototype unit more as a Phase IIa carbody; the IIb’s (or “III’s”) had two widths of sheet metal for the housing and no snow shields.
