I need help identifying this SAK

[Groove]

This SAK belonged to my Great Grandfather, I remember watching him use it many times back when I was a little kid. My Mother found the knife, along with te rest in the photo in a drawer today and she's set it aside for me, I can't wait to see it again! Any Idea what make it is?

That red Swiss Army knife in the middle is most likely a Wenger/Wengerinox. They really did not give names to them that much back then so no idea of what model it is.
