U.k. made, upgraded oil filter screen to fit 1973-82 Triumph 750 T140 Bonneville and TR7 Tiger models. Note that the gauze is longer and the taller gauze mounting sleeve will prevent sludge from re-entering your oil system. An inexpensive upgrade to prolong your investments life. Will also fit some oil in frame T120 and TR6 650 twins without the center pick-up pipe. Do your homework!
