Sanusi SP-20,000 Rare Speakers HELP


I picked up this really nice set of all original high-end Sansui SP-20000 speakers from a local. They are in pretty good shape and work other than one of the mid-horns is dead (T-141). This is beginning to seem like a frustrating issue considering I can't find a replacement mid-horn for sale anywhere. Does anybody know where I can find a replacement T-141 mid-horn.
Also all foam is intact on the woofers and radiators, is there anything I can treat it with to revitalize it or condition it. I'm sure I could refoam the 10" woofer but the radiators are unique and haven't seen any refoam kits that would suite them.

Any help is appreciated.

Search on ebay and if you don't find it save the search and it will likely turn up at some time in the future.
Most of the websites that Google brings up are outdated or dead ends.
There is one person on eBay that is selling a set of these speakers complete or four parts. I have offered to pay what they have listed in the eBay description for the mid horn driver. But out of all my messages they have never responded.

I can wait maybe through winter but if nothing turns up by then they will be sold as is, parted out, or I will redesign them with modern drivers and make them a resto-mod project. These speakers are a project to fix and sell, I have no intrest in keeping them.
