Default old scanspeak 15" woofer specs. Help!!!

I have an old scanspeak 15" woofer number 42w something from before the old factory burned down that I lost the specs on, anyone have the specs? It has a cast mag frame, doped cone, and cloth surround. I'd love to use it if I can.

You, are my new God! Not even Scan-speak itself had these specs anymore! I lost mine in a move I made years ago. Thank you sooo much.
