I am probably incorrect, but will share my thoughts. I believe that the 700 is the make and the T is the model. Kinda like saying you own a Volkswagen ... (T700), or a VW Jeta (T700T). You can't actually own a T700, but you could own a T700T or a T700KL (lite model available in some countries). There is a discussion about this on a different forum, and this seemed to be the most sensible explanation.
