Cleaning old slide rules - aurelio - 09-18-2013 I got a Dietzgen slide rule still in a very good shape, only there's a presence of a green patina on the surface of the cursor, I think due to the contact between the metal and the leather of the case.
Edit: It looks like just came out from the factory, 63 years ago, it needs only a magnifier like the ones showed by Kimberly, to help in reading.
