First picture: Broad Arrow: Gummint Property.
WD: War Department
Crown, 75, E: Inspected by Inspector Number 75 at Enfield
X: the Proof mark. Each and every Bayonet was TESTED individually. During this test the blade was actually BENT to a considerable angle and then straightened WITHOUT breaking. A too-hard blade will BREAK in combat. Queen Victoria's British Army had NO too-hard blades.
Second picture: a lot more information and somewhat garbled.
Crown, VR: this Bayonet was HERS: Queen Victoria's. All of Her property was so marked. If a civilian wanted one, he could buy one without Her marking..... or buy one that She didn't need any longer, in which case it had BETTER have a "Sale Mark" on it.
A Lee-Metford Bayonet should be a Pattern of 1888. Some were modified for the early Short Rifles; these were the Pattern 1903, some of which were actually remodelled Pattern 1888s. There are at least 3 variants on the 1888 Bayonet.
This one has been back to the factory at least for inspection on several occasions. The '93 will be the original date of manufacture, but it was inspected for one reason or another in 1895, 1901, 1903 and 1906. Inspector Number 44 checked it out the last time it was in, Number 23 (1903) and Number 9 (1895) prior to that. Inspector (what looks to be) B-for-Birmingham 3 had a go at it in 1901, from the look. It is entirely likely that some of these marings had to do with service in South Africa and equipment being re-inspected on return home. That's just MY guess, anyway.
A lovely old piece! If only it could talk!
