777-300 all have angle flat seats in 2-3-2 configuration (however the range of those does not allow flights to Europe)
77W or 773 is usually used for 777-300ER
777 for either 777-300 or 777-200, 777-200ER
those aircraft that marked as B773 that I have been, typically TG409/410 is always the old biz class
