Hardy Neroda Fly Boxes, update

Back in February, 2010, I wrote a piece about Hardy's Neroda Boxes.  *   LINK  *  

Today I was looking at a couple of the smaller boxes. Whilst they clearly show the 2 different colours available - referred to as "Oxblood" & "Tortoiseshell"; it was noted that the clips were different, both in type and orientation. The Oxblood box has Hardy's 'Holdtite' clips and the other appears to be standard Wheatley type clips. OK, not nuclear fusion, but another detail for the collectors and curious Googlers. see pics:

 

On closer inspection the tortoiseshell box does not have the Hardy stamp on the face. I know unstamped boxes show up occasionally but assumed it was a glitch.
If anyone has seen these boxes retailed by any other dealer I'd be grateful if they'd let me know.
