Just so you know Peter actually called me and we had quite a chat on the phone. He was very happy and he intends to keep the Zed once repaired. He couldn't stop thanking me. Good Karma to you!!
Probably one of the rarer parts nowdays. Take note Benny as you have one on your car that's for sale and the last 2nd hand one on ebay sold for $450 almost straight away.
It is normal for the 2 inch part to move. I would suggest that your Master Cylinder needs reconditioning or cleaning. It sounds like it's sticking. I would suggest starting a different thread and let some of the other blokes chime in.

All that i have is what you see in the photo. There is the thread below which says that allzparts in Sydney had them years ago

Or if you're clever you can actually modify a toggle switch to perform the same function. I used a toggle switch for 10 years with no issue.
If by gone floppy do you mean the switch for the indicators won't hold in place (left is usually the problem because of gravity) if so it's the switch and they seem to be very hard to find. I doubt if what i have will help you. Do the indicators still work?
I would assume that no matter what security you had in place if people wanted them bad enough they would get them. I had both sets of keys removed from my two Zeds late last year and they were parked behind a 7 foot high locked gate in the backyard. I usually always left the keys in them but i don't anymore. I think i may have disturbed them in the middle of the night.
