I agree with john, that is a CY40B or 50B. I service a 1963 CY50B and that thing is about as antique as forklifts get. It worries me that they still use it. I wonder why the seller didn't fix the brakes and lift instead of painting it. I looks like it runs on gasoline, not good for inside use. It will be hard to maneuver with the standard transmission, the steering systems wear out, and if the brake shoes/wheel cylinders need work, it isn't a easy fix. If you are able to work on it yourself and you want this lift, I would offer him just over scrap value for it, less than $1000.
