There aren't any out there right now. The closest you'll get is the Stapleton kit, which is very accurate to the later version. It would work for a season 1 version in a pinch if you fill in the power level buttons and replace them with decals.
I have also read that the very first phasers had a more rose-pink tint to the emitter section instead of the darker red-orange of the later ones, but it's hard to see the tint color once everything is painted up.
