I love odd looking guns. And when I saw a Chiappa Rhino I wanted one. Then my friend told me about its predecessor, the Mateba Revolvers.  Matebafan.com has some good information regarding the revolvers designed by Emilio Ghisoni.

Here is a video of a .357 Unica 6 being fired. The amount of variety in barrel options and caliber changes for one revolver is staggering.
