Looking for Allison IC-20 mid-range speaker magnet

Dear Forum, 
I found a pair of Allison IC-20 speakers in the garbage that need a magnet for one of the mid-range speakers. Does anyone have any idea where I could find one? 

All of the 3 way Allison mid range drivers for models One, Two, Three, Eight, Nine, Ten (rare) can be swapped.

You’ll need one of these, since a magnet alone cannot be had. Ebay for that driver is the best shot.

IC’s from the garbage?!?! Now THAT is the story that needs to be told. Only 100 cabinets in all the world had ever existed.

Even with that said I saw what happened to a few of them and it could easily make a hardcore Allison fan cry!

Could you elaborate?
