Restoring Worlds Smallest Lighter --- AF invention

This mini lighter in missing some parts and it is in general very dirty and in need of full restoration. The lighter is very small only an inch or 2.5 cm tall. It’s the smallest lighter I’ve ever seen. It used to be nickel plated but the plating has worn off. The plating has to be restored. I also need to make a new screw for the flint because it would be very hard to find one.
