This is exactly the kind of information I'd hoped the Attic would produce through conversations with different collectors. Thanks so much, Steve.
Inside the box, the ad reads: "4 corks supplied with every gun, Shrill atomic whistle built into butt, Packed in bright 3-colour cartons."
This ad reads: "10840: Atomic power pop-gun of ultra modern design. Fires harmless cork ammunition with good loud pops. 8 ozs. 10/6."
Steve began collecting space toys in the beginning of the century, and soon began focusing on those coming from Australia and New Zealand. He currently has about 45 different pieces, ranging from space ships to space jeeps to space guns. To see some of his space toys, check out Steve's flikr page: http://www.flickr.com/photos/37407523@N06/
Also, stay tuned to the Attic of Astounding Artifacts; Steve will be guest writing an article on Australian space toys in August! Action-packed stuff!
