I am hoping that someone can help me. I have exhausted all my "Googling" efforts and am unable to determine year of manufacture, value, etc. for my Speedboy Coaster wagon. It is all intact, with a nice patina and in real good shape overall. The mid support carriage bolt has been replaced but do not feel this distracts from the actual value in a significant manner. I have attached a picture for assisting with determining what info can be obtained and anything anyone can provide will be greatly appreciated.
