Information on this EKA of Sweden slipjoint?

[Sazabi]

Any idea on what model EKA it is?  The handle is about 97mm long, and the blade is close to 70mm long; total length ~167mm open.

That makes the knife basically a smaller, non-locking version of the Swede-88, but I can't find the model number of it.

That is a strange one. I have a Swede 88 and it is that size. It has a lock back though. I have no idea what this guy is. Love my 88 though, best food prep knife I own.

Yeah; it's backspring is stout enough to make me want to find a place that has more so I can have a spare.

Here are some better pictures with scale.
