This is a spill resistant pressure vacuum breaker. Production began in 2007. The body is made of bronze. In 2010 a Model 460XL was introduced which is constructed of lead free bronze. The canopy and bonnet are helpful in the disassembly of the air inlet and check valve for repair.
Common repair parts are a very small subset of the 10,000 plus items BAVCO stocks.
