A number of the older Exbor designs by Pavel Hlava are now recently reproduced in fairly large quantities, so especially if it doesn't have a lot of telltale signs of age, expect it to be a modern reproduction and then decide if that is worth the asking price for you.
It's still a beautiful design, of course and as a collector of design I have bought one or two Hlave reproductions in that price range myself, but always knowing that it wasn't a period piece, with all that that implicates.
