I updated my phone purchased in the UK (Clove UK) through PC Companion (by creating the FTF manually) and when I flashed I also ended up with this 1279-4149_R1C (before I had 1279-4727_R5B but this changed when I updated to 757).

Therefore, if anyone in the UK is wondering which version to flash then this one does the trick!

Here is a mirror of my own FTF of this:

(I didn't remove the TA files, so exclude them in the Flash Tool settings if you wish).
