Rectifier is COOKED... has already stunk someones house out...
.. and yes.. its a sheet of masonite under the pf.. its what holds the balls in the pockets.. when you push the coin slide it pushes this sheet up to allow balls to drop.
No steel balls on this game.. they are hard little white and red resin balls.. only 3 of them though.. 3 are missing.
Plan is to get working and a clean up... no restore required.. natural patina is valued more than a crisp looking game
