I just picked up a King Kong Pachinko and for the life of me can't figure out how to open the front so I can get into the playfield. I have a Julie Pachinko, and there is a lever about 1/2 down on the back left that I just push down and it pops open, but can't seem to figure out how to do the same on my King Kong. I can see what looks like the same long latching lever, but haven't figured out how to work it to get inside the playfield.

Any steps on how to get the front to open is appreciated.
