Cast Iron Toy Mail Truck w/Horses Others

I recently purchased a group of cast iron horse-drawn trucks. Group includes several different types of fire engine/ladder trucks, a mail truck, a trolley, and a milk truck. All are horse-drawn (except trolley) and all have separate people/drivers. Reins from horses to driver are missing from all toys. Paint appears bright indicating either reproduction or repaint so I have priced each of them under $100.00 which is very reasonable even for a repro.
