zero chance of these working after a decade of rusting.
I'd guess that without frequent checks and lubrication that these won't work past a winter or two.
I had new kitchen windows installed that had a crank to open/close.
The guy installing the window told me to open/close the window a few times a year to ensure that the mechanism doesn't freeze up.
That's just one simple mechanism that's not exposed to the environment -- imagine thousands of components that gets rained on, dust & grit working its way into every nook and cranny.
I have a Giant Leveling ladder thats stored in a dry garage. I have to keep the joints lubricated with something like WD-40 once or twice a year so that I can open the ladder otherwise it freezes shut.
