Aluminum Helicopter

I recently acquired this aluminum helicopter. I think that is was a friction type pull toy. It is missing the windscreen (I think) as well as a tail tire. The rotors and axels are made of metal while the body is aluminum. The tires are made of rubber on a metal rim. What paint remains seems to be original. There are no markings on this toy anywhere that I can find. If anyone has more information about this toy it will be greatly appreciated!
