This is an excellent, photorealistic model of Luke Skywalkers Graflex Lightsaber from A New Hope, and The Empire Strikes Back. Originally these props were made from old camera flashes, and this particular one was made by a company called Graflex. I was able to purchase one of these actual sabers from ebay, and use that as a modeling reference.
I've looked around, and your not going to find a better Lightsaber model on the net; Just compare it to the other lightsaber models on Turbosquid, its easy to tell which is the best quality. Thanks for looking and good luck with your purchase!
