Pattern 1888 MKII, most of the markings are inspectors marks, with a bend test "X", crown over V.R. for Queen Victoria (monarch at the time of production) and the manufacture date of January of 1900. Here is the site I use to decypher English markings:
Markings on British and Commonwealth Bayonets
I think it'll be an inspectors mark from the royal small arms factory enfield, where the bayonet was made.
Aahh thank you guys
Yes, that is a stage mark or inspectors mark. As the bayonet was made an inspector would check the bayonet at a number of critical stages and each inspector would make his mark in the appropriate place. Some times the same inspector would leave his mark on various parts/places which indicates he covered a number of different stage checks.
