Oh, that is too bad because it's a nice mid. The assembler just damaged the aluminum, right? Not the cone?
I have a single one of those cabinets that I bought. 12" woofer, 6" mid, and a tweeter. Tossed that compressed cardboard—"wood product" is being generous—as it was mildewed, slimy, and disintegrating. Bleh. The seller had thrown out the other speaker because the cabinet was falling apart. Annoying, because the drivers were probably fine.
Stromberg-Carlson drivers are very nice, though. I have an S-C bookshelf (acoustical labyrinth) that I also found at an estate sale. It sold cabinets separately from speakers, and the idea was to put a midrange in as a full-range driver. Which actually works. Nice for the size, and the bass is impressive for a 6", but it really needs tweeters as it sounds muddy without them. The cab has space for them, but covers the hole with a small piece of plywood.
The woofer I was going to try as an open baffle experiment if I ever found another one.
I still have the crossovers (only the one, though, as I only had one speaker) somewhere in a box, but I forgot what it looked like. If you need the inductor from it, let me know, and I'll try to find it. I was going to build my own since I didn't trust the rest of the circuitry, even recapped.
Let me know how yours sound so I know if I should continue on my quest for another one.
