If you look at Laser Know How's promotional materials for the LKH 2300, they show Laserworld and Pangolin as suppliers. Based on that and the look of the exterior of the projector, I'm thinking it's a re-branded Laserworld unit. But it could be something different.
If you can reach LKH, that would be a good start. But I'd also like to hear what Francis has to say about it. He should recognize it if it's one of his.
