Just a Triangle? It was made for a frebrigade orchestra, and is thus also constructed to work like a beer-bottle opener. It is made of an steel alloy called Veresta. It is attached to a handle made of a part of a disused belt, by a nose ring. The nose ring was mounted in the nose of a billy goat for more than 18 years, before Billy was send out of this world, and his nose ring used for the triangle.
This is an example of effiecient resource utilisation in the voluntary firebrigades.
