All the first-class corridor versions that I have ever seen have TSO on the front not FK and all the numbering on the TSO's from NTP (which then get used elsewhere) is 12345. I know it is not game breaking, but it is one of those annoying little details and would this really have been that difficult to fix? I am no expert, but seems like it would have been incredibly simple and so wondering why it was just left for all these years? I guess the answer is the same as for everything else, but this does seem the very definition of low hanging fruit.
The number issue, it's not such a simple fix evidently as it gets "fixed" then a few weeks later shows up again, usually after a patch - you might occasionally see the 142 with the number on front read 012345 as well...
