Iron Wood? I saw this one of 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.
