Heres one to ruin your brain and day ....... Just come across this unusual rule , the measurements are the weird thing . Not imperial , not metric , not anyhting that I can find . On the rule 0-10 is exactly 42.5mm 0-20 is exactly 85 mm ( I have posted this info on one of the Facebook pages as well and so far no luck )
I would say what you have was called either a tailors square or seamstress square made to measure out and cut fabric. Long ago (1880's) there was a company named Stone's System that made them. Possibly researching that would help you understand the markings. I recall them being really unusual.
Its not the Tailors square as its too small . Its only 150 mm long , so far too small for a tailor . Although similar in looks to the big ones they used ........ What others have figured out on another site ..... . 2 inches is equal to 12 of the segments on this rule . ( two inches = one foot, with each of the smallest divisions on the rule equal to one inch ) So its a strange scale rule of sorts , with no reference markings
Well tailors squares came in all sizes, starting at 4 inches. While it may not agree with your findings they were actually made in many sizes and designs. Same holds true to any trade that uses a square from drafting to slate cutters and everything between.
Could you please tell me the overall dimensions of the square? (open) And width of the wood? In inches, please?? Also. is it fixed, or does it fold? Thanks, Lou

It is a 1:6 scale, not at all uncommon.
