1960's schwinn question

[tino]

Quick question. Did all schwinns from the 60's come with the two tone seats with the S symbol? I have a 64 schwinn american I picked up a little while back with a all whitle seat. I'm assuming not from the factory but just thought I would double check. Thanks

some came with the black seat the same as the 2-tone one, and some came with a black seat with the rivets on the side. there were 3 or 4 different frames too,some were tin, some had springs, and some were wire frame.
