Station type updated.
You were right about the
Boughton Water Tank Intersected Station too Ted; the original user-added entry had had two digits transposed in the GR, so wasn't matched properly at the time of the bulk incorporation of missing stations.

Its been rather quiet as regards the discovery of Concrete Rings lately.
But Dusty has now located another:
TP17123 - Middle Dale
http://trigpointing.uk/trig/17123
That takes the total to 27:

In addition, there are two 'possibles':
TP25218 - Ringshill Place
http://trigpointing.uk/trig/25218
which has been reported as a Ring but could do with a log and photo to confirm.
Also, the OS station record for TP17488 - Snilesworth Moor refers to an
'emplacement ring' which indicates that it has (or maybe 'had') a ring.
CJO reports it as possibly missing; a second opinion would be useful
(I should really make an effort and visit).

Bolnhurst
http://trigpointing.uk/trig/755 is a Buried Block and also a
passive station. The link to the OS page for the latter is
https://www.ordnancesurvey.co.uk/gps/le ... n/T1TL0559
This in turn links to a sketch with a handwritten comment 'B/B WITH DETECTOR'.
A detector is an alternative to the OS term 'Emplacement Ring' which
is what we call a Concrete Ring.
So Bolnhurst is a candidate - pity that its not easy to access

I notice that th OSGB36 Archive says "COORDS SUSPECT SEE TRIG FILE", which doesn't help any

No Concrete Rings rediscovered for a while then 2 come along together!
http://trigpointing.uk/trig/17479 Jingle Pot
http://trigpointing.uk/trig/17382 Bleak Hill
Congrats to CJO and MickandKim
Perhaps the Bleak Hill trig might be given a condition of 'Remains'?
Strictly speaking, the ring is an aid to detect the bolt and is not in itself the trig.

Agreed, updated.
