Thanks Gordon, I am restoring a larger size Taylor trike for a friend and we are missing the seat. I am most interested in the brown seat on the left, just between the two blue seats. A couple questions: 1. Can you send a pic of the underside? 2. Is there a seat post? 3. Is it a Troxell seat? I may be interested in one of the two blue seats but the brown one seems most likely to be the correct seat.
