Seat is constructed by using genuine drum dyed leather over a molded 2" foam pad on an accurate steel formed and ribbed baseplate with brackets riveted in place. Authentic style seams are accomplished by first riveting a leather strip to the vented seat pan with holes and then form fitting the leather cover to the saddle, and sewing the cover to the strip.
