this thread is almost a year old and i just found it.
I picked up a pair of first gen model 7's last year at a yard sale. I did some minor restoration work and played them for a while. They sound nice, but have issues with the tweeters. Two are blown and one of the remaining is on the way out. They reinvigorated my interest in the hifi hobby and I'm contemplating replacing the antiquated dual tweeter with a single. I'd have to design a crossover, so the project is on the back burner for now. They have a nice walnut veneer and i like the old school look.
