Royal Mail's 'Post and Go News' webpage was silent about the whole event which meant that we had to rely on the IAR website or unpublished information from Royal Mail, or contact with the postal authorities.
Two days before the event started the IAR site announced that machine A009 would not be at the exhibition, and would be replaced by A004, which would then move on to a new 'to be announced' static location. The Royal Gibraltar Postal Service could tell us nothing about the Post and Go stamps - not what would be sold, nor what 'values'. Information from Jersey about the content of their machine varied according to who was asked!
So what we found was:
The Gibraltar machine GI01 dispensed stamps with their own flag and with the Union Flag (see below for pictures of an original error on some sales):
The Gibraltar stamps are:
Local Standard (22p), UK 20g Letter (64p), UK 40g Letter (88p)
EU 20g letter (70p), Worldwide 20g letter (80p), Registration Fee (£3.00).
The Guernsey machine GG01 produced their own flag with London 2015 inscription, and Union Flag without.
The Royal Mail machines dispensed, variously, Heraldic Beasts, Union Flags, and Machins with a London 2015 inscription. Some Machins with year code MA13 were available on the first day (13th May) but they were replaced with undated Machins which were still in use on 14th.
The Jersey machine JE01 dispensed Jersey Flag stamps with the Penny Black 175 inscription, and Protected Species stamps launched at Stampex.
As before the Receipts carry the logo of the postal administration - except that for Gibraltar which is anonymous.
Errors and omissions
Mike reports that his receipt from machine A006 is dated 10/05/15 - going by eBay listings session 586 was incorrect but the error was corrected by session 606 (see receipt above).
Robert reports: "As you may know on Wednesday at the start of the Europhliex 2015 on the Gibraltar stand the P&G kiosk was printing a mistake on the Collector Set i.e the "WORLDWIDE up to 20g Value had "WORDWIDE up to 20g - I understand this was fixed later on Wednesday, but as can be seen on the enclosed Photos. This was still happening at 12:52 on Thursday 14th."
... but clearly it had been fixed by the time I bought mine!
