In my phone conversations over the past few years Ed was sad there was really no one that could take over the business. His son was a quadriplegic so that wasn't an option.
He spoke of a possible overseas buyer but I felt he didn't want to sell out that way. He never disclosed to me who that might have been.
For awhile many of his gears were available on eBay and he was the seller. He told me he was selling the last of his precision gear-sets this way, and still doing a few custom orders.
Ed's 28 inch Newtonian/Cassegrain is still on ebay as well as a few gears:
Ed has a number of patents to his name and has been serving both amateur and professional astronomy for so many decades it will be hard to imagine our community without him!
Rest in peace, my friend.
