"Upgrading" the original 1960's Era "Tactical" Flashlight...

This is the Bright Star MX-991/U Angle Head Flashlight.
Originally developed for the US Millitary as a replacement for the TL-122,
these have been in production since 1963 for both government and industrial applications.
We'll "upgrade" the bulb to a 30 lumen LED, add some adapters so I can use cheaper "AA" batteries, in place of the original "D" cell ones, and add some foam to increase stealth.
