These are the 27c - 321 Massey Harris Manure Spreaders I got at a local flea market. One has the metal hubs, the other has plastic hubs. I needed to repair the tow rings, and get a worm drive for one of them. I also needed to replace the spring drive on both. I didn't repaint them as the paint and the decals are pretty good. Below is what they looked like when I got them.
