This is a beautiful Victorian antique 12" gauge slide rule ruler made of wood and brass. The tool is in great shape and has no major defects. It is perfect for collectors of vintage carpentry and woodworking tools. The ruler is an original antique and was likely made in an unknown country or region. It is a unique and rare piece that is highly sought after by collectors. The ruler is perfect for anyone who is interested in antique tools, especially those who love woodworking.

The brass and wood has a lovely patina that I have not disturbed. I could not find a makers mark.
