Yep, globes have some dents and I too figured it probably wouldn't be difficult to get most of those out. I don't know what I would do with them other than they sort of fit my MCM motif. Hw would probably let me bring them home and clean them up and try them on my gear to see what they can do. He is thinking $250-$300 based on what he has seen on EBay.
You gotta wonder if your recollection of how they sounded when you were younger compared to now is because you now know what things can sound like.
That's a strong possibility, they were also new back in 68, my hearing was a lot better I'm sure before years of blasting headphones!
Hey, if he'll let you demo them at home for a while, you got nothing to loose!
