Thanks for all the feedback and info! You've pretty much confirmed my thoughts on them - not top-of-the-line and not junk; well-made, but kinda average performance; and I ain't gonna pay off my car with 'em. They're all on eBay now, along with a pair of University "M-8" in sealed (mystery!) boxes.

Guess I'll go back to my planned resto on the AR-2As - I've put them off for too long! Thanks again!!!
