1920s Cast Iron Mechanical Elephant Bank Restoration

I will restore this rusty mechanical elephant bank made by Hubley. The mechanism is not working and it s missing a spring. I started by dissasembling the bank. The parts were cleaned from old paint and rust with laser cleaner I loaned fron W2M laser, to learn more about that you can go to: The pieces inseide the bank were protected agains rusting with gun blue solution. Other pieces were painted.
