In June 2015 English Ebayer agaplatesuk had these plates for sale. He was previously worldplatesuk and foushekas.
They are a strange batch of newly made and unused pre 1973 plates from various places in the British Isles and Ireland plus one supposedly military number. The military number is unlike any genuine military plate and many of them have additional stickers that look like a child added them. The Northern Irish plate is not even made properly with the spacing of the letters being wrong.
Very suspicious plates from a well known seller of fake and home-made plates and you should think long and hard about buying any of these.
