Any one have any good sites for antique tricycles? My friend picked one up for free. It looks IMO old,, maybe 40's-mid 60's? Not sure though,, Ill get some pictures of it soon. the only markings on it were found on the tires. Tires were made by The Ohio Rubber co. Willoughby Ohio. Model tire was ORCO Air King. They are hollow hard rubber tires(not inflated, or solid).
