I have a couple of older Leupolds that I think are from around that time; they were usually referred to as "Euro 30" models, and they both are marked "European 30" on the left side of the turret housing. I don't recall ever seeing or hearing of a Vari-X3 European, so maybe just change your google search term and try again?
Mine are both 2-7x33mm, with a 30mm tube (obviously...), and the adjustments are metric (1 click = 1cm @ 100meters). One has a standard duplex reticle, the other is a German #4. Adjustments are coin-adjustable (!) clicks.
Adjustment range, as in total MOA range? No idea. I seem to recall reading somewhere many moons ago that these were among the 30mm scopes that didn't derive any greater range of adjustment than a "standard" 1-inch tube scope because the internal mechanicals were identical. Perhaps just made with a bigger tube to sound more "Euro"? Dunno; that tube size was much more of a novelty then than it is now.
One of them is mounted on a Brno double rifle and has not had its adjustments touched in probably 10 years or more. It gets shot at least a few times yearly, and has been on a number of hunts; still dead on. The other one sits in a Blaser QD mount and is usually the scope I would pack on a hunting trip as a back-up to the primary scope; it's been re-sighted-in many times over the years, on several different barrels in several different chamberings, but has never actually "entered the fray" as it hasn't been needed. It sights-in easily and with no unexpected surprises.
Nice scopes; I like 'em.
