Firstly, two Airmail labels produced on the same day from different offices in Pembrokeshire, one type 1 perforated, the other type 2, unperforated:
Second, one which should have been an A but through selecting the wrong on-screen options the branch produced an FP label, normally only used when an international item has been returned to sender for additional postage to be added.
Lastly, showing the whole cover, an Airsure letter that has the correct AAX label. These can only be obtained by paying the £4.90 (currently) premium for the tracked-but-not-signed-for service.
The imperforate labels are now appearing in English post offices so we can expect more widespread use of these. The perforated examples will be the less common, especially Welsh, and especially more unusual service indicators. Many of those appearing on eBay seem not to have been used but just obtained over the counter contrary to regulations. The best way to collect these for the postal historian, rather than just a label collector, is on cover or large piece to prove proper postal use.
