I also have a 3C, so if a vertical head does come up for sale on eBay you're going to have to fight me for it! But they are rarer than hens teeth. I have been lucky enough to find a full set of 4PN collets and a dividing head, less the tailstock. But I paid dearly for both. I don't have any of the horizontal arbors and I don't have the right angle table. Did you get any collets with yours? What about horizontal arbors?
