Check the listing for details. Historically Significant Antique Burroughs Adding Machine - Still Useful Today!. Listed at 475.00 USD. This is what is referred to as a Burroughs Class 9 "Portable Adding Machine". It is completely analog, and is hand operated using purely mechanical means to tabulate (add, subtract, and multiply) anything you can think of tabulating. Prior to computers, this is how banks, stores, companies, and accountants would keep track of everything. As the saying goes: "Everything can be reduced to numbers, and numbers don't lie". This particular Burroughs adding machine is fully functional in excellent working condition, and it has plenty of ink left on the vintage ribbon cartridge spools. Also included in the sale is a spool of modern recycled calculator paper, so that you may start tabulating to your hearts content the moment you unpack it from the shipping box! The unit is emblazoned with the serial number "A856711" on a beautifully engraved plaque on the lower front center. This particular model was priced new in 1948 for $100 as seen in the advertisement. Taking into consideration the average inflation rate of 3.44% from 1948 to 2024:$100 in 1948 = $1,310.88 in 2024 ...truly a value for your money; a genuine bargain when calculating the functionality, usefulness, and original price vs inflation and the carry costs of operating modern electronic appliances or other computerized apparatuses! Also, considering its a 76 year old piece of office equipment that likely was put through at least 20 solid years of good use - (until they were routinely replaced with electric versions which were marketed to the general public in the late 1960s through early 1970s) - You are getting something of historical significance that still functions as intended and withstands the test of time. It is worthy of noting that in the instance of a SHTF scenario occurring, wherein all electronic devices might be rendered useless due to EMFs or some other catastrophic occurrence, you may rest assured that you will still be able to tabulate whatever is necessary during those challenging times, and you will have a paper copy to boot... which will probably make you an in-demand person, and you might be able to parlay tabulating services into a barter agreement with others for necessities and possibly even needless luxuries. The aforementioned scenario alone makes this one hell of a bargain if you really stop and think about it all. This will be packaged and shipped with the utmost care so that you and your successive heirs may enjoy this "Portable Adding Machine" for at least another 75 years, assuming you take good care of it and are not in direct proximity to an atomic blast. Any offer will be considered, so don't feel like you might inadvertently insult me, as I may part with it for a mere fraction of the already bargain price at which its currently listed. ;)
