This is a 12th scale weathervane based on the New England whale motif still found along the Eastern seaboard. It works if you blow it!
 
Made of brass and lead free pewter with stainless steel spindle.
 
It comes as seen in the pictures and you will need to supply your own mounting and lead flashing or flashing effect. There are many ways to mount these and it's not really practical to supply the parts used for every method and roof form.
