This is a well-made stainless steel counterpressure bottle filler. Built by Zymico Inc. in California (he's the guy who originally came up with the weldless bulkheads and bazooka screens in addition to many other brewing related inventions). Wayne never released the CPBF as an official product.
Features stainless steel / brass construction and a unique 3-way stainless steel valve to switch between CO2 and beer and a plastic purge valve (black) on the side of the tee
Never used it since I just fill growlers
$40 and shipping would be around $8.00
