Thank you for your very useful response.
My responses to your post below:
I fear that you may be correct about finding any examples, yet I shall
persist when opportunity arises.
Your comments seem to confirm my pessimistic suspicions, and explain
why all my previous enquiries have yet to be fruitful.
John Harrison would certainly been able to tune to a fairly high
resolution, probably to the nearest cent, as he was using a bass viol
and monochords, which he also used to experiment and train "his" choir.
I am certain that I have correctly understood and specified the
precise tuning (derived from pi) which Harrison advocated in
"Concerning Such Mechanism ...........".
It was first published more than twenty years ago, so all and everyone
in the musical tuning communities has by now had opportunities to
examine and test it.
Although many still insist that harmonious tunings should only use
integer frequency ratios (JI); None have found fault with my
interpretation of the tuning specifications.
Many even now accept that musically "consonant" tunings "should beat".
The remaining area of "mystery" is Harrison's final manuscript, which
no-one (to my knowledge) has been able to comprehend or subject to
experimental tests. This manuscript was only recently unearthed.
Details and transcription here:

Although the tuning he proposes in his final manuscript is entirely
consistent with his earlier writings, the bell manufacturing
equations, methods, "radical numbers", and instructions are still
cryptic.
It is unfortunate that the descendants' bell making endeavours also
used the name Harrison, as this has caused many bell enthusiasts to
assume that these bells were made to John Longitude's specifications,
and they have in all good faith reported unsatisfactory sounds.
This has tended to condemn John "Longitude" Harrison's bell-making
ideas as "wrong".
I believe that there is likely to be some useful "hidden" information
in J. "Long" H.'s final manuscript, as despite his unconventional
religious ideas, everything else Harrison researched and invented
eventually has been shown to be valid, from grasshopper escapements to
musical tuning.
