How does one know what model of Boston Vercise one has loaded

Trying to work out what my DBS model is?

Looking at the booklets for the remote control and so on some say

Boston Vercise tm … and the Charging handbook says
Boston Vercise tm DBS And Some say
BostonVercise Gevia tm. and the Remote QS booklet says
BostonVercise Gevia tm / Vercise tm PC
And there is also one lnowm as Boston Vercise genus

Does Anybody know what the different models That Boston have produced
actually callEd And is there a chronological order ?

does anybody know which point in the series they offer
Directional steering with MICC and Cartisian leads
