Hi Ray, I am not an expert, but believe that is is not a Whitefriars swan. Although it's a very similar shape, the graceful lines of the head and neck are almost identical, but Whitefriars swans have much more detail i.e. there is a a "bump" above the beak and the wings are more defined by a wave like shape going towards the tail. On your example there is no definition in this area. It is a very elegant piece though, but afraid I cannot put a makers name to it as swans are generally not my thing. I am sure you'll get other opinions which may help.
