The plaque says "Ezekiel lightsaber by Justin Marshall" Justintmars, unless I'm mistaken? Maybe he could shed some light on the internals? I just noticed the accent LED under the grip.
Colour changing suggests a higher end, newer soundboard, probably Plecter or NEC with a Tri/Quad LED. If it is built by Justintmars, its probably a Tri-Cree. The wood grip and the wood near the emitter, the stand, the display case and the box are all pretty funky, look like custom jobs.
