Congratz John, a lovely addition to your collection!
What makes this dagger even more interesting is the fact that its seems to have alluminium based fittings, on a type 2 i have never seen those before.
So far i only saw the all aluminium type 1 ( guard, pommel and scabbard) and the Alu type 1 one with the same scabbard like yours.

Great to see whats beneath the surface!
