Following Woodsys query about the Sears/Tomy rocket on the Pathe film and relative to my comment on the post, heres my longer response.
Woolworths, an american company are featured heavily in the Pathe short, so I imagine it could well be the store on the film showing the rocket. Woolies probably had a deal with Sears to sell their products in store and I recall seeing the big Sears Moon Rover in Woolies in the Sixties. Equally, Airfix early forays into selling toys in the late sixties were helped by Sears products as seen in this 1971 catalogue.
As to whether the Tomy version of the toy was available, i'm sure it will have been, as the sixties was a boom time for cheap imports from manufacturers in the far east and it may well have represented a more affordable option to the Sears gantry set. Also, Project Sword appeared at a similar time, so this is clearly the toy that Sword Saturn is based on.
