I am glad they have a museum, but many of the early pictures are not correct.
- The 1963 second stage (108) has the wrong exhaust. The exhaust T looked totally different at the time. The mouthpiece is totally wrong also.
- The 1964 Mk-3 is not really the Mk-3 of that time.
- The 1964 Mk-2, the 1965 Mk-5, the 1969 Mk-6, and several other regulators in the 1960 and 70s are shown with hex key (Allen wrench) port plugs. Those plugs were not around back then. There are few of the regulators shown with the correct plugs.
- The 1970 to 1977 Mk-5 Environ is shown with the multi port swivel. That was not available that early.
- The 1972 Mk-3 is also incorrect. That is a MK-2. The dust cap is also wrong in that and several other regulators.
- They totally skipped the original Mk-1, but that is not a surprised since that regulator was totally recalled and they probably dont want to acknowledge that it ever existed.
These are just some of the errors that I notice on the early history. It is great to at least see some of the pictures and a reasonably accurate time line, but it is sad to see so many errors.
Note: I cant comment on the more recent history
