We have three of these that appear to go together and may be replicas from the 1970's line done by a company out of Pennsylvania. I also have several others that have no markings at all and appear to be older.

History
My father-in-law collected these throughout the years from antique shops and garage sales.
Re: Horse Drawn Cast Iron Toys
These appear to be as you say, "reproductions". Similar pieces routinely appear on Ebay and are available from wholesalers by the box load.
