Just acquired a 1" micrometer labeled Gebr. Weyersberg, Solingen in what looks like good condition. I looked up the company name and they were a notable maker of swords in the past, but found nothing about them as maker of machinist tools. Does anyone know anything about them? Perhaps they sold micrometers made by someone else under their name for a period of time. In the pic, above the micrometer is a small micrometer head that's made for measuring inside dimensions in thousandths. The actual measurement is derived by adding 1" to the reading. No name on that one. Both tools came from a box of stuff owned by my father-in-law.
