Can you tell me what motor this is?

[NathanM]

All I have is this old brochure picture. Does anyone have an idea of what model this is? Or even the approximate year?

The actual motor is sitting in my grandfather's shed and I have been signed up to try to get it running again. I figured the first step was finding out what motor it is.

Thanks!
