I thought you may be interested in this e-mail from Ian which refers to the new Machin label and sets some answers to my questions, he also offers some copies for sale.
Is it a stamp? Is it a label? You can't get mint copies and used ones shouldn't be postmarked!
An unannounced new Horizon Label, bearing the Machin Head and with die-cut 'perforations', was trialled only at the Branch Post Office at Camden High Street, in London, on Monday 8th June. The new labels were available only for the Special Delivery service.
The 'label' WILL be included in Douglas Myall's DEEGAM Machin Catalogue.
The story and better images are on our blog (see link below). We have a few FDCs (with cancelled stamps and additional Camden stamp) as shown on the blog. These went through the ordinary mail - there were no First Day Facilities for this new label, Royal Mail didn't regard it as a stamp.
We will also be getting some labels on plain envelopes serviced as the ordinary mail, ie not on First Day envelopes. These will not be FDCs, they will be posted between 15th & 17th June. They will be un postmarked because there is no operational need for Horizon labels to be postmarked.
For those who collect mint stamps, this is as close as you will get: they will be un postmarked. Given the low numbers overall both versions will be going to be sought after.
Some of our customers collect Machins unmounted mint and are not at all interested in FDCs. Those who have not had FDCs will get priority for the ordinary (week 2) usages. I will try to be as fair as I can with both versions.
We are again out of the office from 14-24 June but may be able to monitor emails in our absence. Regular customers for definitives will get priority but we may need to limit supplies to one per customer.
