newbie with question

[oldguy03]

Picked up my 1st LanCay M9 and have spent a bunch of time looking at the M9bayonets.com website trying to figure this out. I hope the pictures are OK, but, my question is that the blade lettering is LanCay which indicates 1st style after Gen Cut blades, but the blade is blackened, not light grey and there is no variance in height at the top of the blade as shown on early models, rather it is straight across like later Lan-Cay lettering. Scabbard has the screwdriver at an angle instead of straight out the bottom and is dated 93 on the connector. This does not appear to be 1st LanCay production as blade color is wrong and lettering does not match later Lan-Cay production. Before these things become an obsession, a little help please. Thanks in advance.
