Great thread and thanks for the pics.
I have one of those that I have beem trying to soak free to get the head to turn. I had no idea that there was a base for them. Looked like it would have to be fastened to the floor to be stable. It is good to see all the attachments that were available. I will have to be on the lookout for some of them. When I get mine loosened up and working I plan to mount an old flattie on it for display. It would be a good use for a cracked block that would have no other value.
