Michigan City, IN |
The October 1902 issue of "The Wood Workers" has an article on this patent bandsaw filing machine, made by Hillstrom Machine Co. We also have seen this patent date on a saw filer from Foley Saw Tool Co., and we assume they bought out the Hillstrom company although a search for any information on such a sale has not turned up anything. |
