Sword and Crown puzzle Legend says
that when the condottiere Sigismondo Mazzacani besieged
the small town of Chiusdino (Tuscany), an ambassador
came and told him: "to aspire to the crown of this
town, you must first free the sword". In other words,
to resolve without bloodshed the conflict, the condottiere
was challenged to free the sword drived into the rock
of San Galgano... The puzzle we feature here is based
on this legend.
puzzle consists in 3 parts: a hoop, a sword and a crown.

able to assemble this puzzle without any problem:
the sword piece as shown, b) fit its handle
into the slit of the cardboard hoop. c) Slip
the crown piece through the sword handle and d) stick
its ends together as shown. The fig. e) shows
how the puzzle should look.
