Model Source(s): Aurora (no longer in production); Airfix (re-issued; try Comet as a source);  Lunar Models, 24" long.

My original Aurora Orion kit has survived the years reasonably well, having lost only one of the tail "antennas." With a little clean-up work and a fresh paint job -- okay, a paint job, period (hey, I was in 8th grade, the kit was white, the ship looked white...) -- and it'll be good. An interior would be good too. Yep, scratchbuilding time.
