Old coffee set from 1960/70 in flamed sandstone cup saucer oval broc pitcher

An old and very nice coffee service from the 1960s/70s. It is made of flamed sandstone, consisting of 8 oval cups and saucers, 3 pull-out bowls, 1 broc, 1 coffee maker and 1 sugar bowl. Apart from a micro-brilliance on a saucer without gravity, the whole is in very good condition or even superb. To be cleaned (see photos). Authentic. Photos are an integral part of the description.
