GB Triangular Postmarks

Nice catch Geoff,
so far, unable to confirm.
Scotland (Numeral 187)

Here it is.. Thanks

Thank you,
no backstamps? senders address? anything?

I am now dubious about Jedburgh, as Scot Triangles were usually prefixed by an "S" (Ireland "I")

The cover indicates a handstamp, not a machine cancellation.

A fairly late use of the triangle, these were often used if mail had missed cancellation for any reason.

Sadly, the links offered to appropriate search lists are no longer valid here on SCF.

Perhaps the clue as to the triangular cancel is the cachet saying from HM ship and a censor mark.

There are no backstamps or anything on the reverse of the cover unfortunately. The tombstone censor is signed V.B.S.
Which ship is this coming off from? The stamp is from 1948 I presume, so just after WW2

Not coming from a ship that I can see,
(c1940 No ship info would be disclosed)
the Triangular should solve it when /if identified.

The Censor mark is from the High Admiralty Office (Since 1405)
Abolished in 1964

'SIGIL:OFFI:MAG:ADMIR:MAG:BR & C'

The use of telegraph codes was phased out from 1924 and replaced by new numeral codes according to a completely revised list so Ken Smiths Post Office lists (https://sites.google.com/site/ukpos...esbycounty/) will probably not cover this 1940s JH triangular postmark. Most of the later codes were three digit/letter codes and I can find no reference anywhere to the JH code being used at GB post offices. One possibility might be JH for Johannesburg? Used as a cancel for uncancelled mail received? Just a thought.

I too considered the JH to stand for Johannesburg. But it is unlikely.

It looks like the item was sent from aboard a Royal Navy Vessel to be carried by air to Johannesburg. The 10p British stamp would indicate it was meant to be brought ashore at a British port for onward carriage by aeroplane. It is likely the stamp was not cancelled properly. These triangular marks were used as inspector marks. At some stage, before being put on an aeroplane in the UK, a GPO inspector noticed the stamp had not been cancelled and used his triangular inspector mark to do so.

The initials may identify the inspector and not the post office.

Another cover but without the triangular mark and sent to a ship I guess? HMS Medway?

Does anyone else feel it strange, that the Censor cachet
appears to be of the same hand as the addressor, and the same ink?

I'm still trying to figure out why we are discussing censored/ship cancels in a Triangle cancel thread...
Don

Because ships sails can be triangular.

Because we're obtuse/acute/right* (* = delete as appropriate).

Don,
it may have led us to where the cover originated,
thence to identity of the coded triangle.

I am having doubts on the authenticity of the article.

The key here lies in the address. Belgravia, Johannesburg, South Africa.

JH = Johannesburg

The 10d franking was unnecessary, as free postage (upto 4 oz) applied to ships in foreign waters during the Second World War. The stamp, a superfluous addition, was not cancelled at its point of landfall. Instead it was cancelled with the closest thing at hand when passing through Johannesburg post office, a "cheap rate" triangular hand canceller.
