Well, I found your post, maybe someone else will... Unfortunately, right now, they might get money faster selling them for scrap steel, and since most people wouldn't even know what they are... :((
Much luck to you in restoring that one, and hopefully keeping that museum open. Maybe some flyers to the local schools would bring some renewed interest... In the meantime, my husband and I are going to make some new oak or walnut pickups for Rosie and fit them with eye bolts... I'll let you know how it works!
