This one is going to be a challenge. Bought as-is not working and in decent shape (from a distance anyway).
From PINREPAIR's site.
Description: 1970 Sega Jumbo arcade game. Pick up the ball with the Elephant's trunk (suction), then point the trunk towards the ceiling. A blower motor kicks in to elevate the ball above the trunk, with a moving metal habitrail in front of the trunk. Time and release the ball, and it falls through the habitrail (hopefully) into a scoring hole around the parameter of Jumbo. Ball rolls back to the elephant to try again. Eletronic circus music via an 8-track player.
