There is a P1907 hooked quillon currently on ebay and located in Australia. It was made in May 1908 by Enfield and is marked "IF" for Princess Victoria's regiment (a/k/a the Royal Irish Fusileers). It is numbered "R 912". My P1907 hooked quillon also was made in May 1908 by Enfield and is marked to the same regiment. Mine is numbered "R 906". That was a bit of a surprise.
