Help assess the "Nomad"

[Norita]

With the help of a consultant well-known auction house in Moscow (in photo) was done here is a description: An old picture of the nineteenth century Europe
53cm x 63cm in frame luxury home! Tree oil (plywood?)

A stunning portrait of North African Berber on the Algerian-Moroccan motifs, executed in favor of European taste. Approximately 30-th years of the nineteenth century, late romanticism. Most likely the work of the Spanish, possibly French or Belgian source (maybe by Godfried Guffens). A great example of provincial primitivism on ethnographic subject. It is certainly a collector's value.

Weight 6kg, I have not opened it, not analyze it. Art looks pretty cool, but the picture always hung in the same house (from the words of the former owner), brought from Spain. Colors difficult to convey quite intense gamma.
Tell me, please, the actual sales price.
