Antique 2-Fold Solid Brass English Rule

As another precursor to the familiar steel measuring tape we all rely on today, these were in extensive use from the late 19th century well though WWII. All were made by John Rabone & Sons, a famous English tool maker, in Birmingham and were found in every woodworking shop. Folded it's naturally a foot long. They are relatively rare today and hard to find. We have about 30 in stock. Looks like a gem.
