Several years ago an unscrupulous person bought a lot of cheap Whitefriars bud vases and ashtrays without the furrows and had them made into inkwells with brass fittings including a hinge.They cut the top of the bud vase and the bottom became a top for the inkwell ,the ash trays usually have a lot of base wear so can be convincing, when you open the top it hits the base sometimes causing bruising so not very well thought out.I hadnt seen one for a few years but i see they are creeping back.JPH.
