Unfortunately the instruction book was not with it when I acquired it at a garage sale. This rule has a couple of different scales to others I have.

Does anyone have an instruction book I can borrow and copy?

Not able to help with an instruction book
But I did come across this information

If you read down the page there is a list for an instruction book for an 01068 listed,and at the bottom of the page is a contact address with Pay Pal instructions.
Hope this helps
I think I gave my slide rule away about the same time as my abacus

Not seen a slide rule for a long time. Bit like vernier callipers. Most people use digital ones now. Still got a analogue one and can read it. Imperial measurement gets you thinking. Was once shown how to use a slide rule, but long forgotten now.

I have always regarded vernier calipers as good for a quick but not fully accurate measure. People jumped into digital verniers as they didn't have the skill to read an analogue one quickly or read one at all. I dislike digital verniers because of their instability. I have gone back to the trusty analogue verniers. I note that you now get third world make digital calipers under $10 in the junk shops.

I can read a normal vernier caliper in not much more than the time most non-tradesmen take to read a digital and no longer have a digital vernier.

If you want to be right, use a micrometer.

As an apprentice fitter and turner,I was not allowed to use a vernier. They were considered inaccurate. If someone did manage to use one, the job did not get past inspection as it was usually under or oversize.

Yes, indeed. I was a fitter-machinist and for machine shop or tool room purposes vernier calipers were considerd suitable for a quick measure of limited accuracy.

I have one that measures in fractions of an inch and it is used regularly to size bolts for which it is damn handy.
