Wow! I bought today the slide rule in the subject! What a marvel! It's a 12.5 standard, but what a slide rule!
With no jokes, please, about dating a slide rule (something similar recently took place when I started a thread about "dating a calculator"; I know Americans use "date a girl" to mean "establish the date to go out with a girl"; in Italian this has no sense, since we use "darsi un appuntamento" and "datare" means "finding the date"), is there a way to find when a slide rule has been produced? From the box, the leather case, the slide, the stator, the cursor I can get no information apart the following on back side of the slide:
Diwa
DENMARK
No. 601-1
Thanks.
