Vintage Pachinko Machine Metal Feet used pair
Iin good shape, with some rust, scuffs and scrapes.
They slip over the frame like a shoe
the opening to fit the frame is approximately 4 inches x 7/8th inches
it fits a Sanyo perfectly. For Nishijin there is about a 1/2 inch of space open so you would have to fill that space (see pic) or screw the feet on.
