Info
Folding ruler with finely detailed inch scale on one side and centimeters on the other side. Seems made of boxwood and silver plated brass. The boxwood has a nice patina, guess from oily hands.
Folded open to the centimeters side, the wood is beveled/sloped for finer drawing. On the beveled slopes, there are indications for fractions. But doesn't seem to be inches or centimeters.
On the side of the ruler there is a range from 0 to 1.70 every 0.10. From the tip of the ruler to the 1.70 mark, I measure approx 518 mm. This would correspond to 1.2 inch, but don't know if this makes sense. Also, the japanese bu comes close. 170 bu is 515.2 mm. Guessing ...
