According to Sheldon Brown, National/Panaracer made Schwinn Super Record tires (which came on my original paramount), so the Panaracer Paselas are probably the direct progeny of Schwinn Super Record tires!

There is probably no need to look for the branding of "Super Record Tires" on ebay as both products were made by National/Panaracer !!

P.S. I had a similar situation with tubulars, I was looking for RALEIGH NYLON EXTRA tires. Well, nobody makes nylon tires any more, but the tires were 270 grams and made in japan, so I'm pretty certain Panaracer Practice tires are the modern equivalent :
