This is the clutch master used for later single line Spridgets from 1967-1980 (1275-1500). This would traditionally be accompanied by a DIFFERENTsingle line master for the brakes and a 1" slave cylinder.
If you have a 1275, then you need the 1" slave, which we have here.
If you need the slave cylinder for 1500 application to pair with this master, find it here.
