Motorcycle Gremlin Bell Hanger.   Black Aluminum Powder Coated with a fancy Irish Cross design. 

Unit comes with ring but does not come with a bell.   If shown in photo it is just there as a representation.   
 
Photo prop is just that, I photo prop used to show size and not an example of how to mount, (Don't drill a hole in your transmission cover as you will have a leaky bad day) - Again just a photo prop.   

Custom made in house by The Dirty Gringo.
