I have a pdf of a POEEJ article on the speaking clock that came into service
24 July 1936 if anyone is interested. I suspect this predates the one under
discussion? I also have a two part article on the Mark 2 built in the UK for
Australia.(mid 1950s)

Hi Clint I think when I discussed this last a few years ago with the
speaking clock designer and David Rooney the man responsible for the time
gallery at Greenwich. The clock is an early quartz unit, probably made at
the then Post Office Reseach Labs at Dollis Hill in NW London. The clock
is quite a beast ! It was found in a skip (Dumpster) having been donated
to a university in the late 1940s, and was refurbished by a local
enthusiast for David. He did a good job because I believe he had no access
to any documents or circuits. I tried to find some information but it
would seem the archive has been lost (vandals !!) It probably contains
strange things like neon ring counters :-))

They also have TIM the speaking clock which has a rack mounted atomic
standard.

the Science Museum. It’s a great collection and they have some of
Harrison's wooden long case clocks as well as his final chronometer, H5.

I am in London England at the moment, playing tourist with the rest of
my
family. I want one day to be a visit to the National Maritime Museum at
Greenwich, which includes the Royal Observatory Greenwich. I am
particularly interested in seeing Harrison's H1 through H4, plus other
high-precision mechanical timekeepers (pendulum clocks, etc).
I know they are at the NMM - their web site shows some of them. But
where
are they located on the site? The NMM has a large main building down
near
the Thames, while the Royal Observatory and related buildings are on the
top of a hill further inland in Greenwich Park. Are the chronometers and
other precision timekeepers on display somewhere in the Royal
Observatory,
or down in the main NMM building? I've spent an hour or two browsing web
sites without finding this particular bit of information.
I figure there must be list members who have visited the NMM, and know
where the precision timekeepers are actually displayed.
Thanks,
Dave
