US Infrared Scope

[brhalltx]

I have a US Infrared Scope (probably the 1950 version, not a WWII version), with illuminator, at least part of a mount, box (big and green, all of this fits in it), power supply (probably not original), battery (original), a pouch, and a couple of other pieces.
I'm sure these are collectible, but are they especially valuable? I've had it for 20+ years, and turned it on once or twice...
