Identifying the maker of tricycles this old (guessing teens to around 1920 or so by the tires and seat chassis style) is difficult at best. There were more trike makers back then that had very similar models. On these strap steel frame trikes not having a head tube, the name was many times written on the frame somewhere. With wear and tear plus later paint layers applied the name disappeared in time. Possibly it still exists under the red paint and a careful removal of that paint would reveal it. Nice antique trike!
