Grin. If it was made in China before 1910... it'll probably be working perfectly at the heat death of sun. I have a fiendish device - a chinese clockwork mechanical flytrap - it works, despite being a device that would make Heath Robinson get the Mister Practicality award... and it works perfectly after 120 years - and it was cheap junk to start with...
Paula Volsky is offhand the only author I can think of who has the fiendish traps rusted to uselessness. Wish she'd written more.
