The HDS Executive Titanium, also called Ra Clicky Titanium normally has a Golden Dragon Emitter. All Lights had this LED.
There are two officially updated Ti Clickies to NC57 that I know. I am not sure if someone updated this light ever to NB45.
In General Ti Clickies are rare today. If there is a NB45 updated Ti Clicky it would be a as rare as a Rainbow Unicorn...
Maybe it makes more sense looking only for a Ra Clicky Titanium in good shape.
