Without seeing it in person I tend to agree with Jay on the 2nd model Luft. Although a beautiful piece, a slew of 2nd lufts with 50th anniversary markings made the show circuit many years back. One quick way to check is to assess the weight of the dagger. The ones I remember were extremely heavy, especially in the grip area. If you were to hold an Alcoso in one hand and this one in the other, you would notice the later is significantly heavier. The others are very nice however.
