Not been asked that before.
My wife has a theory which she maintains is a theme running through them all but to be honest I think she is trying to hard to manufacture something from nothing. The theory is based on all basses being feminine which to be fair to her I don't really disagree with but she has put way to much thought in to it and how that relates to each model. If you ever meet her by all means ask and she will be happy to expand at length on the subject.
I am not a big fan of just model numbers which I think are very forgettable and impart no charactor and de-personalise the bass which I don't see as a good thing.
Naming them takes ages because it is an important statement and forms associations for people and I would like them to be good rather than bad or stupid.
So in short some I have named myself and of the current models those would be: Recurve , Harlot, Salace, and Skelf.
Named by others: Finn. Krell which was named by Kev Hopper.
The J Type named for marketing purposes.
The R Type and S Type relate to the top horn or lower horn in the single cuts. A S Type has the top horn of a Skelf single cut. The R Type the lower horn from a Recurve. Classic is the first version of any single cut.
E Type comes from design input from Ewan Beck. The A Type Krell is the version I did myself.
Border Reiver refers to local history and as a small compact travel type bass crossing borders seemed appropriate.
Think that about covers it.
