Very old maglite?

[Hmmm]

I just bought a flashlight, I think its an old maglite, but the head is not smoothly curved, but angular, the serial number is KA307323, it has a solid aluminum bolb holder and the bolb is very different than the newer bulbs. Its glass is very thick. It has a metal reflector and when I removed the head there was a large spring.

 

[Hmmm]

It might be a kel-lite

Actually I think it is a 3d streamlite.
