Hughes-Owens Slide Rule No. 1777 and Book


Good used working condition. Some discoloration on rule. Includes book and carry case. Inside the case there is a black line (possible sharpie?) on the underside-edge of the inside-flap.

The case upon first inspection appears unmarked on the outside.
But after looking at it thoroughly at a certain light angle it looked like some kind of faded block-style font along the clasp/band that holds the cover flap down. Appears to read something “…..BETH” possibly.

It was really hard to photograph, I had to damp a paper towel and touch the area for photo#1 in order to bring it out enough to catch on camera.
The area has a little adhesive residue maybe, so I wonder if once there was once some kind of mini plaque adhered there at one point in time.
