We quite often get contacted by someone who has a lot of camera equipment to give away, so, perhaps this is a good place to donate it to:
Donate or sell your classic, vintage, or antique camera equipment to the Western Photographic Historical Society. Donations go toward fund-raising activities to support the Society’s non-profit causes. Please note that they can’t pick up your equipment, it needs to be delivered to Tucson.
