The first few (at least two I think, but I'm not sure if anymore than that) refurbished ATW 158s were outshopped with "Welsh Assembly Government" logos. Then WAG decided to change their name and the next few had a gap where the stickers were supposed to be. They then started filling the gap with the new "Welsh Government" logos and changed the ones with WAG logos to "Welsh Government" ones (though I think I saw 158840, the first refurbed unit, with no logo at one point, so the WAG stickets came off a while before the new stickers were applied).
