It looks like the handle was added later. You could use the box in a different machine.<<<<<<<<<< Bad advice^^^^^^^^^^^ ............. Better advice to follow.

I have measured the 3 EM Gottliebs I have and the distance from the metal locking bar on the wood cross member to the inside of the coin door opening is 9 5/8th inches. The handle is exactly like my coin box. The box should drop right in an EM Gottlieb. Measure your coin box area.

Those early SS pins are similar in some ways to EM pins. This coin area must be different. The height of the coin box you have may be to tall for the coin door on the SS pin.

Here is the other factor. The size of the coin door. Later EM pins have the larger coin door. So does the early SS games. The coin box for the 1975 Abra ca Dabra ,will not work in the 1976 Solar City. The early EM coin box has a height of 4 inches. The coin mech parts hit the coin box. A shorter (lower) box will be needed for the larger door pins.

By comparing the photos. Pdman's coin box sits lower in the cabinet, look were the handle is positioned. Is the handle attached lower on the coin box, for the larger coin door.
