Spacerone, just wanted to tell you that your b&w build looks terrific, certainly better than the original--as if fresh off the assembly line. :thumbsup
I've long been ambivalent about the b&w version, because the gray/black version is so iconic and has more visually pleasing adornments. Also, I didn't like the combination of number buttons and the thumb wheel on the b&w, functionally speaking. I guess the original design considered the thumb wheel for only raising the sighting mechanism/aspirator pile, and then you'd press the number buttons for the strength setting. The gray/black version "combined" the functionality. In the end, it's all superfluous nitpicking anyway, because we never see these controls being used.
I imagine if the budget back during TOS was higher and SFX technology a little better, they might have actually deliberately shown off the phaser parts being actively replaced in an action scene (e.g. removing the P1 for concealed carry or swapping in a power pack). Certainly in "Omega Glory" we could have seen Captain Tracey popping in a power pack, as we actually heard him mentioning them and saw them briefly in Spock's hand.
Anyway, your b&w build makes me want to like it more than ever before.
