The Silver Cabinet has dated this piece to the 1910s.
It is clearly hallmarked on the neck for Chester 1912, with the maker's mark of Grey & Co. The powder flask-shaped body has a suspension loop attached to the base.
The flask has then to be reverted before releasing another ball. Sadly, there are only three balls, numbered 1,6 and 8 - shame! It is priced accordingly. There are a few small dents to the body, which is, unusually, unengraved.
