Single left crankarm for the Caramba Double Barrel Crankset if the 1990s.  This silver natural aluminum crank is used, but not damaged.  It has the "Caramba"  name etched on the outer side, but difficult to see from a distance. 

This is a cool desk item that epitomizes the era of garage CNC shops that produced funky & creative MTB parts.

For square taper bb spindle.

This piece has a few dings & scratches & scrapes from use, but no apparent cracks or serious crash of road rash  damage
