What do the markings on the case say?
Any markings on the light itself?
The Velcoro on the case looks a little newer than Vietnam era.
There is probably a patent for this.
I thought the same thing and thought about things back then that had just been invented....
If I'm not mistaken hook n loop (velcro brand name) was devised for space travel during the appolo years along with zipper plastic bags, (ziplocks) bendy straws and toaster pastrys now called kelloggs pop tarts.
Perhaps this light was developed and distributed at the end of the Vietnam period?
Looks like a COB, don't it? Perhaps an inspection light for jet aircraft mechanics
Fulton is still producing their 2D bendy inspection light.
