Brian's IPP Exchange puzzle from 2012 (Washington DC), made from Queensland walnut with fabricated brass and steel elements and springs. comes with original solution sheet and description card.
from the original description on the Mr. Puzzle site:
The challenge is to work your way through the puzzle to find the barrel of oil.
You’ve inherited this oil well from Uncle Bubba who plugged it in a very tricky way back in the 1960’s when oil was selling for under AU $3.00 a barrel. With oil now over AU $100.00 a barrel the challenge is to unplug the well. You’ll know you’ve got the oil flowing again when you find the barrel of oil.
Can you pitch your wits against Uncle Bubba and work out how he plugged the well? You will have to discover a range of tools and work out how to use them, some are very well disguised, to reach the final goal. No physical force at all is required to open the drawer when it’s unlocked. If you find yourself forcing something you are doing something the puzzle was not designed to do.
