I do plan on using the real parts as much as I can. My goal is to make a kit for the gun so others can have one. If I find a Glenross piece for my gauntlet I prob wouldn't use the original because I would be afraid of it coming off or something.
I figure if I make replicas of the found parts it may help people who don't want to wait for the real parts to pop up or may not want to spend the $$$. The camera/gun parts ( as you know) don't come up for sale too often with US vendors.
