Found a nice little antique this weekend, a wooden scribe. The only marks are the ruler along one side, up to 6". The turn screw is wood it appears to be in pretty good shape. I purchased it at the Olde Ivory Antique Mall for only $3. A quick internet search indicates that it's worth much more but might take some effort to identify the maker. And since one person asked, "What are you going to do with it?" I'll probably put it in the workshop and use it to measure and mark out projects. Just because it's old doesn't mean it isn't useful!
