Duck is 16" long from the beak to the tail, 7" tall at the head.  The head sits on a wood dowel and comes off, will ship with the head off. 

The bottom has some lead weights, I assume to make him float right when in use.  There is also a leather "strap" on the front bottom, I assume they were tied together during use with this. The leather strap is broken. You can tell the paint is extremely old. He has 2 glass eyes intact on either side.
