What is a Hammond 1967 H-3 organ?

There's a listing for a 1967 Hammond H-3 on craigslist and I can't find that model on the internet. Does anyone have any information on it or know what model it really is? it says it has 2 keyboards, 132 voices, and 17 foot pedals. The dimensions are 48in.x 5ft.x 30in.
