Rycen,
If you were looking at the police style flashlights, from left to right there is
Streamlight SL-15, Pro-Lite PL-15, Streamlight SL-15x (My First Duty Light), Streamlight 3D, Refurbished CHP SL-20X from John Weibler, 2-5 cell heavy aluminum built like a Kel-lite but no name, 5D Kel-lite, Streamlight SL-35, 5D Mag-lite, 5D Streamlight. There is a 2 C Streamlight and a 2 C Bianchi standing up between the 2-5 cell and the Kel-lite.
The super long police light across the bottom of the case holds 12 D batteries. The tube comes apart in four sections. It has L.A. Screw Products Inc stamped on the tail cap along with police use only stamped on the body.
Thanks
