I would go by frame inspection rather than by assuming anything based on the bottom bracket cartridge itself, since I'm pretty sure that the cartridge could be fitted into any frame.
An English-made frame would surely have English (i.e. BSC) threading, unless it's an old Raleigh. An English bottom bracket shell should be 68mm wide, and should have left-hand threading in the right end of the shell.
