London Mixture is not the same as Standard Mixture (formerly known as Standard Mixture Medium) in any of the catalogs of yore (there was also Standard Mixture Mellow and Standard Mixture Full). The Standard Medium is just that, a medium English, plenty of turkish and latakia, pretty full stuff. London has that full thick "Dunhill" signature taste but it's built differently, I don't know enough about the ingredients to say exactly how, but I don't think london is either as outright campfire-ish or as pungently oriental in nature.
