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 !
