As is commonly known, the Ordnance Survey donated all their Office File trig station documentation
(correspondence, location details, maps, sketches, details of sight lines to other trigs, etc)
to the National Archive at Kew. This happened several years ago but none of the documents
are yet available digitally. So unless you happen to live nearby, the options for getting a
copy of the trig details are limited. Its possible to request a digital copy from the Archive
https://discovery.nationalarchives.gov.uk/ but their charges are excessive (for me, anyway :( )
Others, such as https://www.arcre.com/ and http://www.searcher-na.co.uk/
will do the job for a more reasonable fee.

Of the archive information that exists, the site sketches are of greatest interest to trig baggers.
I noticed that Jon Glew had added several sketches to the trig wiki (thanks Jon) so I've added a
some more. These can be found at http://trigpointing.uk/w/index.php?titl ... edirect=no

A few more to follow, hopefully.

A few more sketches added to the trig wiki, reformatted as a table - hopefully more readable.

A few more sketches added; also a new trig wiki page about Ordnance Survey documents at the National Archives
http://trigpointing.uk/wiki/The_National_Archives

Still a few formatting issues to sort out on the latter but feedback on the content would be
appreciated; e.g. unclear, missing info or simply wrong!

Thanks

I've completed my upload of sketches to the wiki page but Jon Glew
has a lot more in the pipeline. So its worth keeping track of the page:
