[78-L] Sellers of classical 78s?

[Taylor Bowie]

I have  friend who is inerested in buying/collecting some 78s of a cellist 
named   Emanuel Feuermann ...and possibly 78s of other great cellists.

Are there any retail sellers of classical 78s I might send him to,  or 
perhaps there are some record auctions I don't know about which feature such 
stuff?     I sent him Kurt's name already.

Thanks for any suggestions.
