1816 - company founded
1839 - 1st son joined
1845 - 2nd son joined
The company made rifle barrels - unrifled barrels - that they sold to local gunmakers. They eventually added some gun parts for sale, including parts from England that they stamped their name on, iirc.
1846 - started making guns for the military
1856 - started making farm tools
1870 - started making sewing machines (until the 1890s)
1873 - started making typewriters
I think I have this straight. I had to look up a couple of these dates, but I have a book at home on the history of the company.
