This was a long time ago, but as I recall, he referred to hand-selected examples picked out of the general run, and certified somehow as superior performers, which
warranted a higher price. I have no idea if part of the leftovers were spun off to Calumet private-label, but it wouldn't surprise me. Still, either category would have
a relatively good reputation today for softer color work. These of course would all be 6.3 in this kind of focal length. I'm assuming the third grade would have been the 4.5 portrait series rather than true C.E.'s. He also sold Linhof and Rollei back then, so was accustomed to nitpicky pro customers.
