WANTED: Harvard 4A Talking Machine Support Arm

[Phonofreak]

I know this is a long shot, but I'm going to ask anyway. I have a Harvard 4A talking machine. It was the fancy one sold by Sears. What I need is the long support arm. I don't care if it is original or a reproduction. I contacted Justin Schuab of JAS antiques, but these were discontinued by the Smiths. The machine is almost complete except for the support arm. For now, I have the smaller arms, but I hope to find the longer support arm.
