GB, GV1, 1 Pound, Pair, SG478b? MNH

Great Britain, George V1, 1Pound. SG 478b. A nice pair. Mint have not been hinged, see photo. I am based in New Zealand and I'm happy to send the stamps anywhere in the world using standard New Zealand post. However, if tracked/registered mail is required this can be arranged at possibly additional cost depending on where it is going to.
