NOS Red Jiffy Way Egg Scale In Box with Instructions!

For your consideration is this great old "Jiffy Way" egg scale, still in box with instructions never used. Excellent condition, no paint loss or rust. The only thing I can find is what looks like a smudge on the silver arm under w you set the egg. It almost looks like someone put their finger on it before it was dry. It actually looks worse in the picture. However this is a great old piece & your not going to see to many still in the box in this condition! Feel free to ask questions. Thanks.
