Does anyone recognise these please? They are the same shape and almost the same size (a few mm difference only), but are two different shades of blue. They are 4" tall and 5¾" at their widest point. No pontil mark - see base picture. Rim is flat as if cut like Caithness and polished smooth, but not rounded like the Whitefriars soda vases I've seen. I thought the colours look rather like Lemington but I don't know if this is a Lemington pattern.
