This is the Saturn IB displayed at the Alabama Welcome center. It is an actual S-IB first stage with upper stage and spacecraft put together from extra parts. The S-IVB is not very representative as the parts are, in some cases, upside down. The first stage details are good. This display has actual H-1 engines. The Saturn IB at the KSC Visitors Center has simulated engines. Photos courtesy of Mike Jetzer.
