New old stock argus 1431 mk1 housing, with brand new fujinon lenses, NVD marked, and new NNVT NVT5 tubes. Autogated, white, solid all around.
The only major difference between the mk1 and mk2 is the addition of an illuminator on the mk2.
Manual gain isn't connected on this, but they are 3 plate tubes, so with a bit of soldering, you could convert them to manual gain pretty readily.
Spec sheets are included.
