Vintage Albert the crocodile necklace

Is he an alligator, is he a crocodile?  Who knows-whatever he is he will look great drapped around your neck.  We have named him Albert after the crocodile in Live and Let Die and from the way he's grinning we guess he's pretty pleased with the name.

He is a brass base with silver plate and is hung on an 18" silver plated chain to stop him escaping.  He measures 4.5 cm x 4 cm.
