Instructions on the use of carriers from Hibbards, Colorado Springs. Carriers were used to carry cash and also details of credit transactions (before the days of credit cards!). These needed to be easily distinguished when they arrived in the cash office and would be dealt with by different staff in a large store.

The carriers needed to be a good fit in the tube for efficient operation. This card allowed for testing the felt ends and also gives a list of spare parts. "Separator carriers" were to allow automatic separation of cash and credit authorisation carriers.

Replacement "accelerator discs" for ensuring an air-tight seal in the tubes (and so quicker running).
