Engine Tribute Pt. 4

Right another addition to my engine series, this one is I suppose not strictly an engine part but I still think it counts. This time it's a gear used on a go kart to link the chain to the rear axle. I like how the gold finish on the aluminium has been worn away and scratched to make some really interesting textures and colours when blue lighting is added to contrast against the gold.

Not to mention the complex yet uniform shape of the piece it's self.
