Wow this is cool! It would be awesome to learn more about its history. The nameplate (visible at 11:10 [0]) says patented with a date of 1901, which is 10 years before IBM was founded [1]. This was curious to me so I looked up the patent [2], which was granted in 1905. Based on this it seems that IBM must have purchased the rights to this patent and that it was either made or refurbished after 1911.
