From the designer.... 'Patented in America in 1965, this puzzle was originally created by Joseph L. Litle. The idea to make this puzzle came to me after playing with a wooden copy built for me by my friend, Tadao Muroi. The proportions have been changed considerably from the original plan in this new version. This puzzle being styled after a violin and its strings.
The key word here is… “strings.”' NOB
Separate the parts and fiddle back to start!
