Stridsberg & bjork made saws in Trollhattan from the 1870s to well into the 1980’s. The man in the circle is sawing wood on a saw buck ( picture attached.)
They started exporting about 1885, but not in volume until maybe 1907. Production peaked until the depression. Their peak for employees was maybe 400.
I think Now the company is just Stridesburg, and relocated to Near Kallstorp and mostly make circular saw blades.
Good saw that should give good service. Show us some pics.
As to the 3/26, it might be a hybrid metric/inch designation for points and length, but that’s just a guess. Sweden didn’t go fully metric until 1889, and I bet there was a longer transition in the trades. I know a couple of Danish guys who still use (danish) inches.
