Adjacent to this query, there’s a Facebook group where people post photos of postboxes https://m.facebook.com/postboxcollection/
It would be very useful to be able to fill in the blanks, like royal_cypher and potentially collection times. Many postboxes have just the reference number on Osm. Who owns the data here? Each submitter, the group admin, Facebook?

Apologies for derail, but there is quite a parallel.

That doesn't sound very open to me - does anyone know what permission we have to use this data?

Hmm.  Good point.  Most of the data in Ian's database is contributed by the trigpointers - reports of visits to the trigs.  Most of the data about the actual trigs on the site (position etc) comes from the OS.  See this page https://www.ordnancesurvey.co.uk/gps/legacy-control-information/triangulation-stations, which says "This data, which is no longer maintained, is available for use under Open Government Licence Terms."

That page provides a downloadable CSV  giving the names used by the OS. position, type, status etc.  However, the names starting TP seem to be created by Ian, so I think he owns them, just as Royal Mail owns the postcode data.

One solution would be to quote the OS names instead.  Another would be to use the contact page on Ian's site and ask him for permission to use his names.  I'm guessing that he would be happy.
