Thank you, Leni and Bernard,
Your responses have immediately clarified something for me. As you may recall, one of my recent posts requested information regarding the designer E Downey. It is a "three swans vase" by Downey, (who, its seems worked for Vitrea, London) that was made by Hermanova Hut', pattern number 19814, designed specifically for the English market, that I was referring to. Clearly the Walter Crane item pre-dates this vase?? and more than probably was the inspiration for the Downey version, which was produced from the late 1940s. I'll check the copyright position, and try to post an image later.
Regards,
Marcus
