A plugged well by Brian Young

I'm selling A plugged well by Brian Young.

A sequential discovery puzzle made for IPP32 the object is to find the barrel of oil.

I've owned the puzzle since new but unfortunately due to a family member who solved it put it back together wrong and damaged part of one of the internal mechanisms (going to be vague here as not to give any hints or clues away)

We contacted Brian and managed to get it working so can be solved only by the intended way unless you possibly use excessive force to pull it open but I've never tried to find out.

Once opened though you need to do a simple step to reset it again otherwise it won't lock(Easier to explain once solved, as not to give anything away).

The box is in good condition for age except the drawer should sit flush but has around 1-2mm play as shown in the picture. As long as you're not trying to force it open this isn't an issue with the solve just treat it as it shouldn't be able to pull out that 1mm until it's unlocked.

It comes with description card and solution sheet 

Any questions I'll be happy to answer them.

Final amount will be calculated with shipping costs after auction ends and payment preferred via wise or direct bank transfer, I can do PayPal though if needed.

Thanks and happy bidding
