The Calculator Review began roughly one year ago, and at the time I only had a dozen or so calculators. It wasn't until I came across the adding machine I'm reviewing today that I considered taking the hobby more seriously.

There wasn't much on display, but I was immediately drawn toward the Victor Adding Machine.

here. It lists serial number ranges and which year those devices were sold. Mine has the serial number 657128. As far as I can tell, the list covers a variety of adding machines built by Victor, so devices sold in 1933 were much different than what I've reviewed here.
