Rare Lighter Restoration Video

I got this rare lighter from the family to restore (they want to be total anonymous), the lighter was delivered to them along with his remains during WW1, he was wounded in battle but survived but shortly after unluckily he died of influenza along with thousands of others soldiers. I don’t think that we can even imagine what life was in those trenches. A true HELL. This lighter hasn’t been touched since then. For 120 years to be exact. That gives me chills and performance anxiety. So, I do restore this lighter with the biggest respect and doing the best I can, constantly thinking not to overdo the restoration.
