Beautiful Alley! I agree with you on the tric. The fact that a similar jewelarama effect was used on the medical scanner has made me curious as to whether or not this was supposed to be a medical Tricorder.

Here is a list of what I did...
Replaced the metal side rails and the trigger with aluminum parts.
Painted the body with Zynolyte grey primer.
Replaced the graphic in the meter...
