I was going through the collection in aims of thinning it out and came across a Forbidden Planet blaster. It is definitely NOT the red-triggered mass market produced blaster available a few years ago. The one I have was definitely fan made. It has a black, working square trigger and beautiful clear cast emitter with metal bobbin. As I recall, it lit up and had movie-authentic sound effects (I believe it was a repetitive "click, click, click" sound). Anyway, I can't seem to find a way to open it to replace the battery and determine if it still works. I would imagine the end cover removes, but I can't seem to budge it. Any ideas on how to open it? I thought someone here might have a similar model as I think it may be a Coyle blaster?
