Straits MBE with various errors better seen in pairs with and without.
Small "A" error in MBE 1922 overprinted Trengganu.
Kedah MBE 1922 with raised stop after exhibition. I really like this set.
For years these varieties were not listed properly but mentioned in a few sentences. This was probably due to the controversy when these overprints were made as mentioned in the first part of this series of blogs. Many stamp catalogues of the day ignored this whole group of stamps completely.
