Zeppo that 4X4 looks very nice & cool that it has the original box + sheath.I have seen a very similar one for sale(same box & sheath)
A year or so ago Al Mar 4X4's & QuickClip MT's were going for over $200us , with the world financial crisis prices seemed to drop quite a bit. With prices of around $80-$120us. Prices seem to be on the up latterly. So if the tool was on the US market I would think it would fetch $150-$230ish(US$).
I like my 4X4 best but my QuickClip is a highly desirable & rare 1 of 200 pre production models.
Good luck mate they really are nice collectable MT's just not really users
