Here are the pictures of the Volstro Head in question. I have sold similiar heads with less collets, and no spline adapter for more money recently. The collets tend to bring over $20 each, and the spline adapter has never been sold on ebay by itself as far as I can remember. If you want one of these, or have a specific job that could use one, this is probably a pretty good deal.
No afiliation, just a Volstro fan.
