This comes from a 1959 Lockheed-Georgia PR booklet, no further data was provided. It was described as a “Space Scooter,” which would indicate something akin to the Convair “Space Taxi” shown in US Spacecraft Projects #1. However, this looks like not so much an inter-spaceship crew transfer system as a “work pod” for the construction of spacecraft and space stations. The torus undoubtedly contains thruster propellant; possibly high-pressure gas for cold-jet thrusters.
I saw a mention of this item at Cyberzoo

probably in the same PR booklet you got it from
Same art, different booklet. The one I have is a 1959 “Come work at Lockheed it’s awesome you’ll get to wear a suit and tie in the Georgia summer heat and not have to encounter any of those icky girls or non-white types.” Well, some of that was sort of *implied* rather than stated outright….
