Here are some Apollo Spacecraft-Lunar Module Adapter (SLA) numbers for the crewed missions: - Apollo 7: SLA-5
- Apollo 8: SLA-11A
- Apollo 9: SLA-12A
- Apollo 10: SLA-13A
- Apollo 11: SLA-14
- Apollo 12: SLA-15
- Apollo 13: SLA-16
- Apollo 14: SLA-17
- Apollo 15: SLA-19
- Apollo 16: SLA-20
- Apollo 17: SLA-21
- Skylab 2: SLA-6A
- Skylab 3: SLA-23
- Skylab 4: SLA-24
- ASTP: SLA-18
ASTP launched with the CSM-111 spacecraft that was originally planned to fly the Apolllo 15 H-mission. That is probably why ASTP launched with SLA-18.This might help explain why Skylab 2 launched with SLA-6A. The launch vehicle for Skylab 2 was SA-206. Back in 1967, SA-206 was originally planned to launch the unmanned LM-1 mission after the SA-204 Apollo 1 flight (with SLA-5). SA-206 was stacked on Pad 37B when the Apollo 1 fire occurred. After the fire, SA-206 was put into storage, and SA-204 eventually launched the unmanned Apollo 5 LM-1 mission.
Other notes: - the Apollo 1 SLA-5 was modified for use with spacecraft 101 (Apollo 7)
- the Skylab Rescue Mission would have flown with SLA-22
- Apollo 4 launched with SLA-8
- Apollo 5 launched with SLA-7
- Apollo 6 launched with SLA-9

Apollo by the Numbers has all this data.

SLA-7 launched on Apollo 5, but does anyone know if it was originally planned to fly on another flight? It arrived at KSC in October 1966. |

The cancelled AS-207/208 dual launch, perhaps? |

On what pages is the Skylab and ASTP data? |

I have read in a film scene listing that SLA-7 and an FVV (Flight Verification Vehicle) were de-erected from Pad 37B on June 9, 1967. It doesn't say what the launch vehicle was. Apollo 5 launched on January 22, 1968. |

Spacecraft Lunar Module Adapter 7 (SLA-7) is being lifted for mating with the Saturn IB launch vehicle at Complex 37 in May 1967. Shown at the base of the adapter is a LM mockup, which will be used in a fitting test. SLA-7 flew on Apollo 5. |

So the film listing was probably referring to Apollo 5.Not sure which SLA was to be used for the SA-206 launch vehicle that was erected on Pad 37B less than a week before the Apollo 1 fire at Pad 34 in 1967. The SA-206 launch vehicle was de-stacked after the fire. |

The mockup shown in the Apollo 5 fit test is one I have not seen in any other photos. Which LM mockup was it — an M-series, or LTA-series? quote:

That seems to be a good theory. The SA-206 launch vehicle would have had a nose cone on top of its SLA. Instead, a CSM was on top for Skylab 2, thus some modifications were needed, hence the change from "SLA-6" to "SLA-6A." Clearly, SLA-6 was modified. However, one must wonder why Apollo 5/SA-204 needed to be launched with SLA-7 rather than SLA-6. Perhaps not knowing if another unmanned LM flight (LM-2) was going to be needed or not had something to do with this decision. |

The list at the start of this thread makes possible a deduction on which SLA hardware could still be in existence.The two Saturn 1B test flights with CSMs used SLA-3 and SLA-4, respectively. The three cancelled lunar landings also leaves three SLAs unused for Saturn Vs. Three SLAs are attached to the existing Saturn Vs, though I don't know if SA-500D had an SLA designated with a standard SLA number (SLA-D/F, or SLA-FVV — as in flight verification vehicle — perhaps). Then there are two Saturn 1Bs with SLAs, SA-209 and SA-211. SA-209 has SLA-22 attached to it for the Skylab 4 rescue launch vehicle. Reportedly, SA-209 is displayed with the FVV SLA. There was an SLA set designated simply "SLA" used for testing purposes. An SLA was used with CSM M-11 as well. Lastly, SA-212 was completed and presumably had an SLA. Saturn 1Bs SA-213 to 216 never had their S-IVB stages, so presumably SLAs were not built for those launch vehicles. |

I think you are correct. The Apollo Spacecraft Chronology Volume 4 has an entry for November 4, 1967 that lists the six Apollo missions that were planned for 1968:
- Apollo/Saturn 204 - first unmanned test of the LM in earth orbit
- Apollo/Saturn 502 - second unmanned flight test of the Saturn V and Apollo CSM
- Apollo/Saturn 503 - third unmanned test of the Saturn V and Apollo CSM
- Apollo/Saturn 206 - second unmanned flight test of LM in earth orbit
- Apollo/Saturn 205 - first Apollo manned flight, a 10-day mission to qualify the CSM for further manned missions
- Apollo/Saturn 504 - first manned Apollo flight on Saturn V. This mission would provide first manned operation in space with both the CSM and LM, including crew transfer from CSM to LM and rendezvous and docking.
