Here is a picture from my Apollo. Looks like you are missing the dinger.

Some of the match unit machinery has been replaced with parts from an older game. The bell clapper is that loose thick washer on a peg thing. The bell would be mounted on a different bracket that allows the clapper to ding it. Here's the match unit in a '64 Soccer:

Looks like you'll want the stepper spring kit from PBR along with the bell clapper and e-clip. Clapper spring 10A-183 isn't in the kit so get one of those too.

The loose looking thing on the left is the clapper. From this picture, it looks to me like the bell is adjusted too far away from the clapper. Loosen the screw on top and move it all the way over toward the clapper.

I've seen instances where the coil sleeve on these is metal and the plunger won't pull in far enough to move the lever far enough for the clapper to hit the bell. You might want to replace that too.

As far as I can see, your unit is complete but just out of adjustment.

Here's a picture of the unit on Top Hand, which is the AAB version of this game.

That's a Williams number - 1969 parts catalog, page 2. PBR has millions of little bits that aren't online. That spring is one of 'em. Ask for a bell clapper and the spring that goes with and you would get the right one but having the # shows you're trying and they like that.
