Occasionally we get pictures of tools and we just don’t know what they are. We love that — and love to check out what folks have dug out of their stash and try to ID it. In this case, reader Glen sent in a picture of this bit of steel. To us, it looks like an adjustable fence or guide. My first thought was that it was part of a shoe for a saw, but the pin and tube on one end is really throwing me.
The markings on the left side read “R2871 DET 2” if that helps at all, but it didn’t reveal anything helpful in our search. What say you Toolmongers? Can anyone help Glen out and tell him (and us) what this is? If so, let us know in comments. You can’t do any worse than we are at the moment.
