With regards to the "mod note" based on the number of views it was added without actually comparing the files.

The postal files are genuine files extracted from 1030 packages and NOT the 1025 files with links supplied at the beginning of this post.

The 1025 file specs are: Country Date Time Size
Great_Britain 13/02/2019 13:28 9,725,471 bytes
Nederland 13/02/2019 13:29 2,069,956 bytes
Singapore 13/02/2019 13:29 494,577 bytes

The 1030 files I have supplied
Great_Britain 08/05/2019 06:67 9,742,866 bytes
Nederland 08/05/2019 13:16 2,069,847 bytes
Singapore 24/04/2019 16:03 494,494 bytes

The build date of the file shows they are a newer version and the size shows they are not the same file. The only editing I did to these files was a name change. Nederland and Singapore files are for whatever reason slightly smaller but the Great Britain is just under 17.4 Kbytes larger. Doing a search of a recently added postcode will confirm however even though the file is newer it is still about a year behind. eg postcodes AB130AW and AB130AX can be found in my UK file but not in the 1025 version but were introduced in June/July 2018
