Anyone know a good trade area for old electric organ parts?

Hey, I posted this for sale over in the other area here, but does anyone know of any site, page, mailing list or such, that deals with old electric organs from the 1940s-1970s? We've got some field-coil speakers out of an old Baldwin, that we need to get to a new home somewhere...

Thanks!

Regards,
Gordon.

Here's a rather phenomenal source for B3's
http://vintagehammond.com/, but I can't know if they'd be interested in the old Baldwin speakers...

Good luck!
