K&E 4058 --- 10" Box Wood Mannheim Slide Rule
Original Box with Early Framed Cursor
From an eBay sale in August of 2007. The rule is now in the collection of Clay Castelbury.
This version was probably produced between 1900 and 1910. The cursor is made of celluloid attached to a metal frame. The box is a simple cardboard box with printing directly on it..
