It became the paymaster machine in the 1950s. The paymaster machines are still currently sold. On the cover of the machine: "F and E Check Protector." The machines were manufactured in Chicago by the Herburt Heidman Manufacturing Company. F and E (Fessler and Evans) were the distributers. The box also contains business cards and case. One card is for business analysis and the other for the Sam Stoole construction company. The case has a brown leather cover with "Sam Stoole" in gold lettering. There is a note pad on the inside.On the first page is written "Sam's reminder book." The remainder of the pad is blank. Also contains a name plate "Sam Stoole, P.E."
