Here's a beautifully crafted old carpenter's scribe. It's un-branded, but clearly factory-made of precision brass and rosewood. The running arm features a brass track with a thumb screw that adjust the width between the two scribing pins, while the set block has a brass thumb screw to adjust the inset from your straight edge. Used for scribing the locations of mortises, rabbit grooves, etc. This beauty is ready to go to work in your shop, or just as suitable for display in a fine tool collection! Selling used, as-is. No warranty given or implied. See the pictures and ask questions.
