Indian Motorcycle logo Concho in bright shiny Nickel.
Originally used on leather saddle bags and other leather accessories made for Indian by Mulholland Brothers. That's back when Indian Motorcycles was in Gilroy (1999-2003). Indian was very strict about quality and tolerances and and required made in USA materials- these conchos passed with flying colors.
The concho is 1 5/8" wide by 1/4" tall at center. It fits an 8/32 machine screw- available at any hardware store. I'm not including screws because everyone will need a different length to fit their application.
