Hi Dave
I agree with Tom that it looks like you have an Eickhorn crossguard on your dagger but not a Type-2 but a Type-3 .
If you use the link to Jon's excellent reference it should be a Type-2, but if you take a look at this link http://www.heeresdolch.de/html/parierstangen.html
you will notice that it is a Type-3 crossguard.

Regards,
Jori
