Vietnam War Trench Art Lighter Restoration Repair

I was sent this trench art lighter from Vietnam for restoration. It s made in early 70 s. It s been somewhat oxidized but some parts have stayed in pretty good shape. I started the restoration by disassembling the lighter. During the disassembly the screw holding the body together broke because it was so badly rusted. This was no major issues because it was easy to replace it. This time I chose to use rust remover to remove the oxidation and rust from the parts, other than the lighters tank. The tank contained sort of porous material to hold the gas so I didn t want to fill it with rust remover but I sandblasted the rusty areas of it. Then I sanded it up to 2000 grits. The links lost their blueing so I needed to reblue them. I heated the links with a torch and dropped those in oil. I used oil intended for chain saw chain but it doesn t really matter.
