This puzzle was originally designed by Adam G.Cowan, who offered the master files to other puzzle builders. Frank Schwartz and also David Calzone are two known builders of this puzzle.
My Bicone is exactly the puzzle, Frank presented in the forum.
This was about one month before he stopped building after being diagnosed with Leukemia.
So it is probably the last one he ever made. I'll keep this in honour and will take special care about it.
