I have had several, but no good ones for quite a long while. I used to get anywhere from 25 to 50 for them, depending on condition. They are frequently twisted.
I have a customer in OH who has over 125 of them. He keeps talking about selling them off, but I do not think he ever will. He also have over 400 4 inch adjustables.
P. S. He is not just blowing steam about his numbers. I have seen pictures of his collection.
