Hawk Models 1939 EMC Switcher

I think that is more representive of the EMC SW switcher, not the later SW1.   

The SW had a similar box to the SW1 on the front, which I have heard was a sand box.   However, on the SW1, the entire hood was shortened creating a "front porch" and the cab was moved in on the rear creating a "Rear porch".     On the SW the cab is in the same place as the NW2 and later SW7-9 prototypes.    The hood is shortened but only enough for the box.    The whole front of the hood is not moved toward the rear.   

General Models also made a model of the SW that is very similar to the General Models/All Nation NW2 kit but has the shortened hood.    I saw one of the kits new in the Spotlight Hobbies in Kansas City in the early 80s.   I think that was the name of the shop on the south end of the city I visited a few times while traveling.

The photo below shows a stock AN NW2 on top and my kitbashed SW1 below.    The dimensions are based on prototype drawings.    Note the "porches" on either end of the SW1 compared to NW2.  

Do a search on the SW and you should be able to find some drawings, also the SW1.    I can't put mine in here for copy right reasons.
