What a great article. Thank you for sharing it. I am sure that most of us have a love of vintage machines. I have 2 Singer treadles one authenticated to 1906), a Featherweight Singer 221 and a Singer 401. I don't think I will get to 400 machines. That pocket machine is fascinating. There is a family museum here in Colorado that have a washing machine collection that is great to see. Your trip to their home should be wonderful.
