The bottom of the swan is "waffled" so it will stick to the metal base better. There appears to be some type of glue holding them together. From what I have been able to find it is probably atleast pewter. Also it is likely a salt or master salt. The only ones I have so far found though researching is glass base with metal wings. But the lion head angel mark on the bottom I have not been able to find any info about... I'm quite sure it is a swan on water, made to look that way anyway. Surprised no one has any info though.
