it all depends on the model...
a -300 is a "SEVen TREE TREE"
a -400 is a "SEVen TREE FOW-er"
a -800 is a "SEVen TREE AIT"
but I have no idea what an NG is
So I guess, I would have to go with Seven Three... as its the closest.
Apologies for the cryptic writing, but I was going back over my old FRTO notes and found the section on pronunciation
