Actually, the one picture with a tweeter in it shows that it is, indeed, installed correctly (with the tweeter itself toward the outside). Too bad about the dent in it though.
The date thing isn't quite as egregious as it first seems because 1967 IS when Advent was created. It's just that the Advent Loudspeaker wasn't released until 1969.
The surround issue is the biggest gaff. Orange County Speakers sent him the wrong surrounds (or he ordered the wrong ones). The ones he used are for the masonite woofers because the outer flange is much wider than ones for the all-metal woofers.
The wider flange interferes with installation on all-metal woofers because the ledge for the surround on the basket is only about 1/8" and then starts going toward the gasket area at an angle. The flange on the surrounds is about 3/8" and, so, won't fit into the ledge. When you try to attach it, it will wrinkle on the angled surface.
It also appears that the surrounds are the thick, rubbery type with a small roll when they should be ultra-compliant (really floppy) with a 17mm-18mm roll.
Obviously, the woofers in Mr. Dudley's Advents had been replaced at some point but he used materials and procedures meant for masonite originals.
All that being said, it was still an entertaining article and it is wonderful that he wrote it and Stereophile published it.

Actually, your are correct about the tweeters and I was wrong. I had to check though. A while back I had installed mine backwards and then made the correction. Funny, I remembered doing just the reverse of what I had actually done.
Generally, I was pleased to see the article. All the points made about the surrounds are valid. My guess is that the surrounds were ordered according to the model and not the actual style of woofer.
My speakers are equiped both the masonite and the metal frames. Both styles seem to function pretty much the same. As a pair of mine (or even the featured pair) indicate, the metal frames were often used as replacements.
