Following the update of Ghostbusters.com, two brand new Slime Blower pictures have surfaced. They should proove to be pretty handy as they’re good quality shots of the Slime Blower and of the backside of the tanks.
simply put…awesome. Wish these were around a year or so ago 
nice to finally see the other black box on the gun. It’s barely visible from the limited shots in the movie. I wish they would display them somewhere so someone can get pics
I think it’s safe to say that the two pieces on the butt of the blower gun are quick release fixtures, simliar to the trap quick releases, only much larger.
Over the next few days, I’m going to start revising the current set of plans, to make them more accurate to the new details shown in these pics.

They’re Parker quick couplings.
I guess that answers the questions we all had in where the hell the Slime Blowers went. Sony still has at least one of them in scuffed condition.
Beauty!
Are those a certain type of project boxes on the blower? I also notice the lights were removed (?).
Just something I’ve noticed is where I work, I see all kinds of smaller motors (12-14" drive motors for the machinery) and they all have small boxes like these with the small lip (usually an access panel of sorts) that follows the contour of the motor casing…if this makes sense? Perhaps that’s what these are?
Makes sense to me… gonna look into it.
EDIT:
Looks like simple parts to scratch built and vac-form.
