I received this arm from member "maurywhurt". It was rather dirty and still had a little paint on it, he wanted it rebushed and thought that it already had a bushing in it that just needed replaced. Well it turns out after I cleaned and glass beaded it that the entire arm is a solid piece of bronze, anyone ever seen one like this? It was on his 1966 model (I think), it has the proper part numbers and all. I've never seen anything like this or even heard of anything similar to it.
