Has anyone purchased any of the blue prints from Master Replicas or any other online retailer...specifically the one of Luke's ROTJ Lightsaber hilt?

If so...

Is the quality good? Are they detailed enough to create a prop replica from them? Do they include the measurements etc... I mean if I took one to a machinist...could they duplicate the prop from the blue prints? I would love to see an upclose view of the Luke ROTJ lightsaber blue print...even just bits and pieces would be nice to help me determine if it's worth buying.

Can anyone help?
