Hello,
I think it is a regional work. Central Asia sounds likely to me, as some members confirmed. But that is a debatable point, because it looks like a marriage/composition. I'm agree with that, ariel. But all parts except the blade are of a central asian or maybe caucasian origin (in my opinion) and I don't think it was made in the western world. Daggers from Central Asia were shown, which are made of recycled parts, too. This and some Bichaks with similar scabbards are arguments for this region.
What is your guess were and why it was made?
In every case it wasn't made recently to deceive anyone. The seller was no collector and the price was (very) moderate
Regards
Robin
