A "tourist" version of the Paramount with a 3 or 4 speed SA hub option was offered until sometime around 1965. I've only seen two come up on eBay over the past couple of years which would suggest that they are less common than the racing and touring versions. In one of the Schwinn history books (the title escapes me right now) there is a picture of a bike described as Frank Schwinn's personal Paramount. It is an internal hub version.
