So after moving to western Canada I visited the local museum. Not once but twice I found National Cash Registers. National was a company that practically invented these cash register and were the only ones making them. This is significant to me because they were made in Dayton Ohio, which is close to where I grew up.
I put info on the two that I found in the image descriptions if you want to know more about the models. Also, I found out while researching these that the wooden ones are called "Woodies" and that made me laugh.
