Rusted PERTRIX FLASHLIGHT restoration

In this video I restore an old rusted flashlight. I bought them from an online auction house. During the restoration, the first thing I did was to dismantle the components. I removed the rust with a sandblaster. Then I painted the parts black glossy. I polished the brass battery contacts and polished the bracket above and coated it with nickel. When all the parts were finished I put them back together. At the end, a slightly modified battery was inserted. Music from YouTube Audio Library.
