[Elrick]

Good day!

Dear forum users, I have a trivial task, ask the Board /assistance.
There is a collection of 13 Hanukkah candlesticks, the work of Israeli artists, bronze. Basically - the first half of the XVIII century, a few pieces - the end of the first half of the XVIII and XIX. Provenance: private collection of Maximilian Goldstein, one of the world's largest collectors of Judaica beginning of XX century. During the war, that part of his collection, which has not hit in the Lviv Museum of Ethnography dispersed in several private collections, in particular, these candlesticks - a collection of PO Krivoshei.
Examination, journal publications with images, the conclusion of the Lviv Museum has

There is a desire to sell this collection, with the whole, namely as a collection, which has not only historical and cultural, but also a ritual value. But there is no clear understanding of where and how it would be more correct to do: London /New York? Moscow International Salon? Jewish society?
Also, as more or less reliably determine the actual cost today? Enter the auction houses to open the way, look for local experts who know the subject? Iudaku established markets in general, and, especially, at such unique items, of course, no. There is information that a few years ago for this collection predalagalas _ochen_ significant amount, but do not know how this information can be trusted.

In general, Can you please tell how to approach the problem.
Thank you!

Best regards,
