Tim,
I liked your paint job so much, I found a place that had CITADEL TIN BLITZ paint and am in the process of repainting mine. I still have to add the black top coat, but I think the TIN BLITZ color more closely matches how the prop looked on screen.
Seems like this has happened to me before...with Klingon TOS gun -- I paint 'er up, and then come across other reference that nags at me to repaint. Uggghh.
Anyways, after looking at screen caps again, the pistol does seem to have an overall brown/bronze color to it, and as nice as my gold/black paint job looked, your paint job seemed to more closely match the actual piece. Thanks for sharing pics and paint techniques.
I'll post a pic when I get mine done.
Of course, now watch someone come along and do a licensed version of this piece.
