Hi, I saw that post, but I don't think he didn't actually says he wanted to swap feet. I will contact him to clarify, but I read the post as he was looking for/wanted the other type foot than what he had. Which is what I am trying to do too, but we are looking for the opposite foot. Ideally I want to have them both as they are the only two feet ever made for this machine. APQS only ever made the scoop/spoon foot and then Ms Butler personally had the ruler foot made. But she only had a limited supply made and I'm hoping to get one before they are all gone. But I'll write to the other poster and check. Thanks!
