ITT Night Vision NE 5000-1 Gen 3 Goggles Working Condition Computar Lens

Description

!!  Please read this first I previously listed this saying there is a small hair like line when you look through the unit. Since then I blew it with light air and the small line went away and now there are 2 tiny specs visible. I do not know how to clean it I am assuming it is just dust since the tiny hair like line disappeared. I have no way of taking a picture through the unit to show view my android phone just won't do it I have tried many times
The view through the unit at night is excellent I would not list it in this condition if the view wasn't as it should be!!!
Selling a Gen 3 ITT NE 5000-1 Night Vision Goggles
This was used by a police department was taken from service in working condition
Includes hard case with pressure relief knob from ITT
Includes NE 5000-1 shown in pictures in very good condition it has a Computar Lens on it that is the lens that came on it. It also has another 300mm Computar lens in the kit and a 3rd lens that I have no idea what it is.
There are a few adapters and a owners manual
I only tested it with the lens that it came with it looks like the other Computar lens could just screw on but the 3rd lens I don't know if it needs a different adapter because the threads look different.
As for condition it is physically excellent with no visabal damage. I put 2 AA batteries in it and went in a bathroom with no windows and I could see fine with it and the IR also brightened everything up when switched on.
There is a small visabal mark when I look through it off to the right side that looks like a tiny hair. Could be a scratch or dust I have no idea and I don't want to mess with trying to clean the lenses.
