Columbia Booklet/Manuals --Originals A PAIR !

Description

In the late 30s the Groetchen Tool Corp  had a problem :  their Columbia slot machines were jamming and were hard to work on.
To help operators, they sent two booklets to help.  One was for instructions  and the other had real photos of the machine with arrows and numbers so the mechanic could read what had to be done. Follow the instruction and the part number and find it on the photo.
These two booklets were under the desk of an operator for over 50 years !   Originals as clear as the day they were born. Each of these booklets is dependent on the other.
You receive both of these booklets for one price. Keep them in or near the machine because if you sell it the buyer wants to know how to keep it running.  A jamming solution is explained and looking at the part that has to be adjusted, you would never know that was the secret.  I know !  After 3 hours trying to unjam the machine, I finally looked at the instructions and there it was  !! Duh !
This machine was ingenious at the time because if a person could slip a 5c size slug into the machine he would not usually get away with it because when he got a winner , he would get back the coins he had just put in.   5c in those days would feed a family so making slugs was common.
When a replacement part is needed, these booklets usually point to the part needed and the name.  Columbias were made of, what at the time, was called pot metal and it did not hold up over the years and would crumble under stress.  Thus, Columbia parts are expensive and rare.
Keep these booklets TOGETHER with the machine.  The large one shows pictures of the parts, but the smaller one tells HOW to fix the machine.
