Hi Lukey, welcome to Outdoorking.
I'm not completely sure what you have - some pictures of your mower would help. I think Deadly Dave's machine is a Tractor 8, and I think that is much older than an Anniversary 8. I'm also not sure that remarkable lever on Dave's machine was made by Greenfield - not only is it way too agricultural, by my reading of the IPL the Tractor 8 did not have a hand-brake, just a latch on the foot-brake.
Here is the park brake mechanism for an Anniversary 8:

Here are the numbers of the relevant parts:

Please post some pictures of your machine, so we can identify it, and the parts of the park brake mechanism you do have, so we can understand what is missing.
