I have a Guinness branded stout faucet for which I would like to use a different tap handle. All of my other faucets have the simple black handle and I like the clean look that gives. My nitro tap has the big Guinness handle which I would like to eliminate. I know that I have seen an adapter that allows you to use regular (american style) handles on a Guinness faucet but I can't seem to find one anywhere. Does anyone know who sells these?
