Got it working for 4.14.1, now I understand why my wife chose an IT job, it's fun and addictive.
Turns out since this mod is quite old, I had to user an older version (pre 4.12) of ship.ini entry for IJNBBGeneric, the difference is subtle, yet it makes all the difference.
Replace the exiting ship.ini IJNBBGeneric entry with this dinosaur:
