Can anyone point me in the direction of a maker for this little late art nouveau style vase? Its silver top is a little bashed but the hallmark suggests it's from London 1912. The maker's mark on the silver is DL, which would fit for David Loebl at Schindler & Co. It has three of these triangular motifs around its top. Its base is flat, it is 20 cm tall (8") and it weighs 225g. Sorry the photos aren't too good - it's resisting all my attempts to focus properly.
