Iron Wood?  I saw this one on eBay and sent a message to the owner.  They inherited the tool from a deceased relative and they didn't know much more than the name on the tool.  After a few questions, they wrote back saying that the instructions are labeled "Smithy".  So, it looks like Smithy now has two models of the Super Shop, one that is 110-220 volts, and the other is 220 volts and that the 220 model is labeled Iron Wood.  I don't get it.
