Help Identify this Enfield Bayonet (IMAGES)

[apocryph]

My grandfather and I were rummaging around in one of his old WWII footlockers and found an old bayonet (without sheath) that I've determined to be a Lee-Enfield bayonet. It most closely resembles the P'07 design, but none of the pictures I've seen quite match it. My grandfather claims he picked it up somewhere during his tour as an American figher pilot in the European theater, but beyond that he doesn't remember.

Here's the whole thing:

The cypher appears to be British, with barely visible 'VR', which I presume means it was made during Queen Victoria's rein, between 1837 and 1901:

Is this right? Am I correct in assuming that "4 '98" indicates it was issued in April of 1898?

Here's the opposite side of the blade:

I've read that the mark that looks like an upward-pointing arrow is a government acceptance mark, and that 'EFD' indicates it was made in the Enfield factory. Is that correct? Any idea what the other markings mean?

Here's what I assume is the serial number on the pommel:

Any help identifying this piece is appreciated. I've no interest in selling it, but I would like to know as much about its origin as possible.

It is a Pattern 1888 - looks like the Mk III version, for the Magazine Lee Enfield, but your photo of the grips is a bit dark. The Mk III grip scales are attached by steel bolts, where earlier patterns used brass rivets. The X stamp is a proof mark, indicating the blade withstood a bending load without failure.

Thanks Daniel. I appreciate the info.
