Rusted Petrol Lamp - Restoration

I found this FireFly Petrole Lamp to flea market. This is an old Petrol Lamp made in France manufactured by Guillourd to Nantes.
This old Lamp was so rusted and i didn't want to buy it because i was thinking that there was nothing left to do to save it, but the seller made me a good offer for it and i didn't resist. Only 1 euro.
I spend so much time restoring this Beautiful Lamp but worth it, what do you think?
Luciole in france means FireFly
