Here are photos of one Ed recently sold to Josef from Austria, a long time Star Trek Prop, Costume & Auction Forum member, and the photographer and layout designer of the Battlestar Galactica Auction catalogs.
The COA from Ed states:
"This document certifies that the Star Trek Assault Phaser Prop pictured above was fabricated by me for the film "Star Trek: The Undiscovered Country". It was returned to me after the production was finished, and has been my personal collection."
Josef says the Phaser is made out of resin (Confirmed by Ed) and has 3 metal parts; the tip, the rear fins and the knob on the side. It is in very good condition with only minor scratches from production use. It did not come with a base plate attached, something Ed had allready mentionend in the eBay description. When he asked Ed if he could make him a replica, he told Josef that he never made the plates in the first place, they were fabricated and applied by someone else (Greg Jein). Also, the plates on his Phasers were simple stickers, not metal plates as found on the hero versions.
