I've only seen ones in pictures that enthusiasts have built for themselves. Its not out of the question to build one, I am "guessing". For example, the stick on a Spitfire looks easy to reproduce.
I "guess" one could buy a cheap stick (like the Thrustmaster Flight Stick X that sells for under $30 in the USA) and use it for "active" parts. A trip to "Home Depot" (in the USA) for raw materials, "maybe". But, I've not done it -- so this is just speculation. And, one does have to be "handy" with tools -- or willing to "try and fail". Thing is, on something like this, trying and failing does not have to be real expensive (under $60, I guess) -- maybe worth it for the "education" to a person who has the time to spend.
