Since this thread is persisting, John has given a (tentative) KOF ruling, and the listmeister hasn't shut it down yet, I'll add my information.
I have a 1989 Schwinn Lightweight catalog, which describes the Waterford-built Paramount, including the new Paramount OS. I also have a Paramount OS bicycle, done up in Team Wheaties/Schwinn livery and parts. While the catalog does not name the tubing manufacturer for the OS frame, I understand that it was made by True Temper, to Schwinn's specs. The three choices of frame material, according to the 1989 catalog, were:
-standard-sized Columbus tubing -Schwinn-specific OS steel tubing -aluminum
The lugs on the OS are very nice, indeed!
Those wanting to see a few photos (no detailed ones yet) of my (lugged steel, maybe KOF) OS Paramount can visit here:

There you will also find photos of several on topic bikes and projects, including my '38 Durkopp, a circa-1925 Bon Star (Ozzy scorcher), 1969 Flying Scot Continental, 1975 Major Nichols track bike, a 1954 Ephgrave No. 1, 1952 Hobbs Blue Riband, etc. etc. Even a '70s touring bike by R Sachs, both on topic and a much-revered KOF. I've also scanned and uploaded my circa-1925 Reynolds Tube Co., Ltd. pamphlet.

As it is lugged steel, it could be considered KOF material. But I don't recall that 753 was ever available in oversize diameters. With the conspicuous lack of tubing decals, I'm with you in thinking it is probably True Temper.
