Within my files I found at least one (I do have a lot of different VOOS plain blade armies in my files) which I think does resemble the first one shown here.
It´s from an earlier thread 8perhaps gone to time) from or member Roy Caroll and was offered for sale in january 2006 here in the for sale section.
For sure a different dagger as it has a different (color, no hairliner) grip.
Unfortunately the pics arn´t larger.
