Perfect and lovely, to suit just about all Triumph pre-unit engines, to my knowledge. Styled after the Webco/Jomo racing valve body of the day, this verion is fabricated completely in rust-free, tarnish-free stainless steel. Besides looking great, it also protects the protruding pressure relief button from damage in case of a fall, which was its original intent.
This listing is for the body only, you'll need your own guts to complete.
