This little viewer was
manufactured by DCMT Ltd (Die Cast Machine Tools), originally of
Palmers Green, London, England in 1956. The viewer itself was called the
Space Viewer, but card subjects were taken from The Lone Star Magazine
and included Steve Larrabee (The Lone Star Rider), Captain Cutlass,
Rocky Stone & Space Ace.
In 1952, the DCMT company hired an
ex-army actor called Roy Green to tour in the role of Steve Larrabee to
promote their cowboy based products (including toy die-cast guns). He
remained with the company until 1961.
The character' Space Ace' was
produced by Ron Turner, who later worked on The Doctor Who
magazine and a Stingray cartoon strip.
