the following links show what I'm talking about how would one model this setup

this shows both sides of the non boxed version

and here is the boxed version and yes it is 2 separate boxes I had to take a double take to make sure

showing the other side and if you look you can see it is 2 separate boxes do these have vents/screens somewhere on them

wow, those are some cool borg-like NWs!

I would guess that those are the paper air filter contraptions one would find under the boxes on the roof of GP38s and the like.  Given the age of NWs they would have come originally with oilbath filters tucked under the hood.

Seems odd MKT didn't blank out the centre windows....what could you possibly see thru them now!
