Some of the older model sextants used half mirrors instead
of the modern see-through mirrors that make it possible to
have the sextant picture a sunset at LAN. The older
sextants were harder to use.

You being old and retired, I figured you'd probably have
some antique instruments.

Actually, I never used this method, except in an "emergency". The
normal method used, was to get a couple/few morning sunlines and do a
running fix by moving them up along the course line and crossing them
with the LAN sight.

Now, with your explanation, Neal may be able to get a Local Noon sight.
Maybe, I'm still not sure he aware of what we are talking about. Hitting
a high noon fix with the Earth traveling over 900 MPH is kind of like
catching a Fly with Chop Sticks.

OTN your method is the correct way to take a Noon Sight. Even the
instruction that came with Neal's (Also mine) Sextant explains the Noon
Sight that way.
