Pattern 1907 Bayonet British made by Wilkinson. The Pattern 1907 Bayonet was approved in the United Kingdom on the 30th January 1908, with a straight and single edge blade and a hooked quillon, no clearence hole was implemented. Production levels upto 1911 for the P07 bayonet indicates estimates of: R.S.A.F. Enfield (EFD / ENFIELD) - 175,000 Wilkinson Sword Co. (WILKINSON) - 25,500 Sanderson Bros. & Neubold (SANDERSON) - 22,500 James A Chapman Ltd (JAC / CHAPMAN) - 14,200 Robert Mole & Son (MOLE) - 13,300 The hooked quillon was removed from the 29th October 1913 as part of implemented changes, as bayonets were returned for service the hooked quillon was removed. The Crossguard shows a slightly different and 'pointed' shape after removal compared to P07 bayonets manufactured without a quillon. It is very difficult to guage how many P07 hooked quillon bayonets still exist, it is likely only a small percentage of the hooked quillon versions are avaliable today and their respective collectability and value is ever increasing. The other significant change we see with the P07 was a clearence hole introduction in early 1916 with bayonets returned for service modified to reflect this change. Again it is difficult to gauge the numbers of P07's that have not been altered with a clearence hole, is fair to assume that a minor number of P07 without the clearence holes is in the collectable market and adds value, rarity and intrigue to the display. It should be noted that these example without a pommel hole would have likely to have had a short service life. By the end of the Great War the following is guide to estimate total production figures for the P07 bayonet: Wilkinson Sword Co. (WILKINSON) - 2,360,000 Sanderson Bros. & Neubold (SANDERSON) - 1,600,000 R.S.A.F. Enfield (EDF / ENFIELD) - 500,000 James A Chapman Ltd (JAC / CHAPMAN) - 300,000 Remington Arms (REMINGTON) - 100,000 Robert Mole & Son (MOLE) - 60,000 Vickers Ltd (VICKERS) - 10,000
