I did a bit of research and it looks like the Royal Mail (or rather the Post Office) stopped making these stamps as of October 2021. Can I (or my father for that matter) still use these stamps to send Recorded/Signed For 1st Class mail?
For example, if I want to send a simple letter in a C5 envelope, can I just put 1 of these stamps on the envelope and get Recorded/Signed For 1st Class postage without paying anything extra? Obviously I presume I would need to take it to a Post Office to get a tracking number etc.
Many thanks for any help :)
