Pretty sure that is a copy/knock-off from the late 1970s from the time when Pflueger itself still manufactured in USA.. Japanese-made, like various others such as one sold by Herters, from an unaffiliated manufacturer. Phillips head screws, cheaper aluminum alloy for the plates, more fragile plastics for the drag plate and, especially, the latch cover and winding knob. Don't know how formalized licensing agreements were. Somewhere around this same time, Pflueger itself offered a less expensive reel, with similar cuts in material quality, and less expensive Japanese manufacture, the green/gold Progress. The reel shown may be a licensed cosmetic variant of that and or the Shakespeare Omni. viewtopic.php?f=4&t=13648&p=84041&hilit=green+Pflueger+progress#p84041
As to the Orvis mentioned above, that wasn't a copy or knock-off. That was a spec reel manufactured by Pflueger for Orvis with variant cosmetics (and label, of course), the same frame, same drag mechanism, but a different lever-based adjuster.
