What is the current location of Link-built Apollo Mission Simulators?

Question

I was confused about the final disposition of, and even the number of, Apollo Mission Simulators built by Link Flight Simulation Division. This question is not about any simulator built by any other organization.

As a former Link employee after the Apollo era, I always believed that there were four Apollo Mission Simulators - two Command Module Mission Simulators (CMS) and two Lunar Module Mission Simulators (LMS). One CMS and one LMS was located at Kennedy Space Center (KSC); one CMS and one LMS was located at the Manned Spacecraft/Johnson Spaceflight Center (JSC). This picture shows one CMS and one LMS located at KSC.

However, I was wrong about this as shown in this very useful partial answer.

Here's what I know about the disposition of the simulators at this writing:

• JSC LMS - in the museum at Marshall Space Flight Center (image source: personal photo)
• JSC CMS - in the Science Museum Oklahoma, Oklahoma City (image source: http://www.collectspace.com/ubb/Forum29/HTML/000978.html)

(These two simulators look very little like the historical image above. All the visual equipment has been removed and they look like small, stripped-down versions of the flight modules)

• KSC LMS - Owned by the National Air and Space Museum, loaned to and on display in the Cradle of Aviation Museum, Garden City, New York (image source: https://www.cradleofaviation.org/history/exhibits/exhibit-galleries/exploring_space/grumman_lunar_module_simulator.html)

• One KSC CMS - Owned by the National Air and Space Museum, in storage in the Paul Garber Facility. Confirmed at the NASM website. In March 2023, this simulator was reported to have been returned to the former Link factory in Binghamton for restoration and display.

Does anyone know how many Link-built Apollo Mission simulators there are (this part has been answered), and where they ended up (one KSC CMS is still unaccounted for)?

Additional, possibly useful info

• Historical picture of the JSC CMS
• Historical picture of the JSC LMS
• Historical picture of the KSC LMS

(You can tell if a historical simulator picture is from KSC or JSC by the walls of the simulator room. The KSC walls are covered by smooth, acoustical tile or mesh. The JSC walls are less finished with exposed girders and roll-up doors. The access steps to the CMS are also different in the two facilities.)

• KSC LMS writeup from the Cradle of Aviation museum. It claims only one LMS was built.
• Article on the JSC CMS from the Field Guide to American Spacecraft. One of the museum signs pictured claims three CMS's were built.
• Article on the JSC LMS (not named as such) at the Marshall museum. From the Field Guide to American Spacecraft.
• Techworks Museum page on the LMS
• A Link press release from 1968 describing the simulators. Annoyingly, doesn't say how many there were.

Answer 1

Here is a Photograph of the KSC CMS Simulators (x2) and LMS Simulator in the Flight Crew Training Building, from 1968. I toured this building in 1971 with flight crews training in both the CMS and LMS, but cannot recall if there was more than one CMS at that time.

The document Mission Training Program for the Apollo Lunar Landing Mission also confirms 2 CMSs and 1 LMS at KSC, and 1 each CMS and LMS at JSC.

The most important as well as extensive CM crew training will be accomplished on the Command Module Simulators, one located at MSC and two at KSC.

The most im­portant and extensive LM crew training will be accomplished on the two Lunar Module Mission Simulators, one each, located at MSC and KSC.

(MSC = Manned Spacecraft Center, the original name for JSC)

Answer 2

Don't know if it can help. I found a box with many documents from NASA Gemini and early Apollo mission. Was doing some research and end up to your post. I've got one photo (NASA S-64-20810) taken in April 1964, showing a scale model of Apollo CMS. The notice said that "Two mission simulator assemblies will be manufacturated by LINK; one each to be installed at Manned Spacecraft Center, Houston, and at Atlantic Missile Range, Cape Kennedy. Not sure if the simulator shown is a prototype or one of those seen in the picture. I can share better quality pictures if you find some interest for your search. Have a good day.

EDIT: I better look to the picture, and you see on the background a rolling chair. So definitely a small scale prototype of the CMS that will be later build by LINK.
