The Antique Vintage Felt & Tarrant Comptometer Adding Machine probably from the 1920s is a rare and valuable piece of American industrial history. This mechanical calculator, made in the United States, showcases the craftsmanship and functionality of the era. With its intricate design and historical significance, this adding machine would make a unique addition to any collection or display, offering a glimpse into the business practices of the early 20th century.

These were part of my father's antique collection, and I don't have any more information than what you see in the pictures.   I am not sure if the piece works fully or what functionality to expect.  What you see is what you get, I just know he cherished these items very much and I hope they go to someone who will also appreciate them as he did.  We have listed the item with the best description and knowledge we have.    

Shipping cost is higher because I will no longer use US Postal Service.  They have lost/damaged 3 different antiques in 2026 plus multiple delays and I am not willing to allow them to continue to  ruin irreplaceable items. Package will be sent via shipped by UPS or Fedex, depending on which is best cost compared to best service delivery time.
