There were two Eickhorn original Yugo Air Force Daggers on Ebay.

One, offered by a member here, is probably the finest example of a maker marked Yugo I have seen. It did not sell and I suspect will be relisted.

Original Yugo

The second is a parts dagger made up of left over parts with an Eickhorn double fullered blade with no scabbard release. As a general rule you can not give this version away for $300, but the seller wants $900, now $800. My guess is he is playing off the price and quality of the original.
