Can anyone give me any information on this heater?

I am just curious how it works, how old it might be, are they safe to use in a small but ventilated area? I've already got a 502 stove and a dual burner 413 I think. They're both dated from the mid '70s. I'd like to get this but just don't know much about them. I thought it'd be good to add to my collection.
