I was recently sent a link by blog friend Terry H for a Space Bird No.3, the vintage Japanese Probe Force 3 toy.
In the description were these Japanese characters, which you may find useful using in Google searches of your own if you're interested in the Space Bird.
There was also a name mentioned, Tsuyama, which could be a makers' name, but the boxes of these toys show the initials YT so I'm unsure what it refers to.
Here are some of the Space Birds I've saved photos of over the years from various online auctions including a couple in the Moonbase collection. The cockpit, engine and jet colours vary. The final shot is of the white version.
Have you got a Space Bird?
