The 1:24 scale Gemini model kit by Revell yields many noticeable detail pieces. The round bump thingy as seen on the top of this pod, Eagle Two has only four of them, one per pod, while Eagle One has eight of these things on the pods. The black rectangular thing on the upper outer edge of the pods comes from this kit as well. The Astronouts in the 44" Eagles (and 5 inch moon bugy) also come from here.
