Help me identify this Yale forklift

I aquired this older, manual transmission Yale, 4 wheel, 2 stage forklift.
Guy that sold it to me didn't have any information about it's model, age, capacity, etc.
Obviously there is no plate, or I haven't found it, yet.

I'm asking the experts here to help me identify the model or give me a clue of where on the unit I might be able to locate model/serial/vin number.

Here is the link to pictures: http://ift.tt/2iSUL3q

Thanks in advance for any information.
