Here's my Revell 1/48 Gemini as Gemini 7. I used Rick Sternbach's excellent decals. The black stripes on the adapter section are decals from his set.
I scratchbuilt the radar elements on the nose as well as the hatch interiors. In addition, the thrusters just aft of the capsule were all scratchbuilt, to update it from the kit. The horizon sensors, antennas, and the boom magnetometer, out of the aft adapter, were scratch built as well. And the gold foil on the back end, was from a chocolate bar wrapper.
Thanx for looking
Pete
