Sorry, thought I had already done the feedback! This is a wonderful machine - I just use it in my tax business .....I know, using a mechanical adding machine when you already have a computer, well its more than that to me. I've been in the tax business for over 40 years and not once during those years did I not have a calculator on hand. Or for that matter, an IBM Selectric Typewriter - not sure I could do my job without both of these "old style mechanical pieces". Thanks guys - great machine at a very reasonable price.
