The pictures are of an old tricycle that has been in the family for years. My dad used it as a kid (he was born in 1927), but I think it is older than that. My guess is that it may have belonged to my grandfather or one of his siblings, in which case it is pre-1900. The frame is made from strips of steel riveted together, and the wheels are solid rubber with a wire running down the middle. The pedals are also solid rubber, and the wheels and pedals are retained with cotter pins. Any idea how old this is, and what brand it might be?
