I think these were the best joysticks ever made! Im biased because they were made in Australia
I havent got a spare to offer you, but maybe you could also source the Star Cruiser, which if memory serves was very similar design, possibly the same tough mechanism bt it has a smaller rounded casing.
I'm in the exact same boat. I would love to get my hands on at least one of these joysticks too! I used to use them all the time as a kid on my C64. I don't know if it's bias Voyager. They were really good joysticks
Multicoin Amusements Star Cursor - MCA-201 is what it's called specifically.
