Harry's Headache by Harry Nelson - VERY RARE

This was the exchange puzzle of Harry Nelson at IPP14 in 1994 in Seattle, Washington.  Your challenge is to put all 27 cylinders into the box.  For the "maximal challenge," you may work ONLY through the small hole in the lid.  

This puzzle is VERY RARE.  I have been unable to find any time it has ever been offered at auction.

The puzzle is located in the United States, but I will ship worldwide.
