I am currently restoring a Fun Land and am curious about the bell assemblies for each machine. The schematic for the Fun Land has one bell for 10 points and one for 100 points, (as shown in the second photo). I guess no bell is heard for single points scored.
The Fun Park is the Add-A-Ball version of Fun Land. It is shown in the first photo. This game has 3 bells as shown. I don't own the Fun Park nor do I have a schematic to determine what the third bell is for.
