This kit is intended to be used with any Airfix Saturn 1B kit to portray the SA-204 LM-1 launch vehicle. It includes a replacement SLA and nose cone, replacement fins and first stage engines and many detail parts to really superdetail your model. The resin parts are solid, with the exception of the hollowed out engine nozzles. They are molded with crisp details and no visible airholes. All resin parts will need to be removed from their pour plugs. Extra parts are included. Some of the resin parts are identified by numbers molded onto the plugs. Photoetched parts are identified by numbers etched next to the parts. You won't use all of the photoetched parts and extras of some of the smaller parts are also included. You'll need to do some minor work to the Airfix parts to accomodate the New Ware parts. The decals provide the SA-204 specific markings to supplement the Airfix decals. The instructions include a short program history and are divided into sections: Lunar Module fairing, second stage and interstage, and first stage. Each section includes both wraparound and detail drawings showing where the replacement and detail parts go. References are also included for photos on the New Ware web site.
