16mm Television Test Films CBS c.1969/74 x6 Early Thermal Cameras & Simplified Operating (see below)

Not really sure exactly what I have here!
There are a total of six - 16mm films ranging in size.
Film are all on reels apart from one which is just wound.
I've tried to show some images representative of the film - a couple of the films are quite 'abstract'.
Most are test films - paterns / thermals images/ etc, except large purple reel film which seems to be instructive.

Purple - large reel is marked CBS - A television recording - prog : Simplified Operations - Practices - CBS California etc..Also in film title includes "Simple Operating Practices for Two Cameras"
Brown film lead-in is marked - Low Light Level / TV Demo / Rar /Orig / 500' / Heads' - Autonitics (13 March 1969)
Small grey reel is marked 'Early Thermal'.
Silver case is marked Thermal Imaging 16mm B&W mute prints & neg  - copies 1 & 2. (although can't confirm this is accurate)
 
Approx reel sizes are:
purple  30cm, brown 18cm, silver reel 18cm, black/red wound 13cm, grey 9cm, black 9cm.

Films appear to be in very good condition for their age (50+ years). They are untested - just inspected the first section of film at the start of each rell. Please inspect photographs carefully. If unsure please ask questions before bidding.

These are heavy so shipping costly.

Please see my other vintage photographic items.
