Yes, yours is an old cabinet that was converted to the latest 6300 (Super Six Plus 2) series. The original 5000 series cabinet gets carved up in order to install the 6000 series electronics drawer.
The two pushbutton switches use # 658 miniature lamps with a wedge base. They are 12 volt bulbs. Do NOT any other number bulbs in those sockets as the lamp driver circuitry will be damaged.
The coin door lamps can also use #658, #194, or #161 miniature lamps. Take your pick, but I would suggest using 658.
