Help with unmarked SMLE Bayonet

[Jenko]

Wondering if anyone can help with this SMLE bayonet. Its none maker marked, its has got the X bend mark, scabbard looks like a WW2 one. The overall finish on this bayonet is a little rough with no real finishing off performed there is even a burr on the muzzle ring the blade has a phosphate type finish and the blade has no factory applied edge on it. Even the bayonet catch although neat has gaps all round it something you dont see on WW1 bayonets. I have had a little look on the web and found one on WD militaria titled as an ersatz ww2 bayonet, in the same scabbard and appears identical except it has brass rivets in the grips. Any comments welcome.

I have read that wilkinson sword refurbed some bayonets by sandblasting but the jurys out on the blackened finish,it was authorised by the admirilty and black painted finish was acceptable in the field to prevent rust.
Afganistan made a copy with brass grip rivets and china made one with no markings so more digging needed im afraid.
