Just in case you are comparing your knife to the Model 1 in the catalogue...

The reason it does not look like the Model 1 in the catalogue is because whoever ordered it paid extra to get Stainless Steel (standard is tool steel), Black Micarta Handle (standard is leather), and the Brass Butt Cap (standard is Duralumin). They also asked for the Commando Handle shape (no additional charge) instead of the standard straight handle.

They also paid extra to get the Black Sheath.

You got a nice knife!
