This is an Old Puffer Mechanical Bank. The Bulldog's mouth opens up when you pull his tail, you put the money inside his mouth, and he swallows it. I am not sure how old it is but im guessing it's a reproduction. His eye's are made of glass. T is a marking on the bottom, but I am unable to read it. The front of the bank says Ole Puffer and the side says Cigar Nickels. This would make a great addition to any mechanical bank collection. Please see attached pics.
