This antique folding ruler is a beautiful addition to any collector's inventory. Made with silver metal bound ends, it measures 12 inches when fully extended. This is not made of wood and there is no manufacturer mark on it, but is marked with No. 39. In great working condition with tight joints and legible marks and numbers on the inside fold. The metal caliper fits tight but moves smoothly in its grove with the marks and numbers being very legible. You can tell this was a hard working piece of equipment in its day but also was carried for and appreciated. Don't miss out on adding this piece of history to your collection.
