Thanks for these, Joe.
The photo with the sign 'set your watch' is especially interesting for me
as it shows a pair of old clock displays the same as one I have here. These
are the two digital displays that are showing the same digits. There's part
of a third one the same on the extreme left but the display on that one is
not visible in the photo. My clock has a different mechanical dial on the
ten turn pot at the extreme right of the front panel- otherwise the unit I
have here looks identical to those in the photograph.
I have never been able to track down any info on this unit. Mine came from
a US military installation here in NZ (Black Birch) that has long since been
shut down. It's certainly old technology- RCA 'numitron' displays and mostly
TTL circuitry. I've had it running here continuously now for about six years
driven from an HP 5245M timebase - the clock has never missed a beat.
(recent quakes excepted ) Also. one of the newspaper cuttings in that
collection you posted mentions the flying clock being down here in NZ to
visit Mount John, a magnificent observatory site in South Canterbury. These
days it's a well known astronomical observatory run as part of Canterbury
University Physics Department.

Some time ago, a local Amateur gave me a CD with some radio related
information. Also on the CD was some information from when he was in
the Air Force. As it is Time Nuts related, some of you might find this
of interest. I have posted the images in my Dropbox and will leave
them there for a few days before removing them. Several images are
large.
