B is for Bruder . . . Kinder, Hans Postler et al . . .

And to be honest, Giodi should have Kinder's slot above as they made them, and they don't only seem to have supplied Kinder, but other people as well, while my 'third source' is Cose Progetti Promozionali, who may be designers (albeit copyists) as well as importers?

This is a very small sample of the Bruder mini space vehicles, and there are quite a few more, but this is an overview which will call on the past finds of Moonbase Central too! As far as we know Bruder were first with these as part of a wider range of otherwise civil vehicles in a distinctive red-yellow-orange-blue-green scheme.

Woodsy found this set in Rosita branding from Spain, which seems to contain Bruder product in different colours; Bruder state on their website that the confectionery trade were good customers for their small toys, so they clearly did a fair-bit of contract manufacturing.

And here's a Hans Postler set (last image) in standard Bruder colours

And there's more here

While these are the Giodi for Kinder copies, again, not sure it's all of them, but you can see (with the lander) how reverse colour versions are available. Although when I say copies, they are all new vehicle designs, but based on and aping the Bruder colours.

Flight-line; Bruder and two Giodi/Kinder, folding/swing-wings, the Bruder are about 50% bigger by mass, and probably wouldn't fit in Kinder eggs, or at least some of the parts wouldn't?

Giodi clone; the paper slip states Cose Progetti Promozionali (Modena, Italy - 'Promotional project things') and they are straight-out copies, slightly smaller still, you can see a few differences between the Giodi and Cose (bottom right), but they are the same design, and made in China (possibly the Tennison Trading in the links above?) so imports which other capsule providers may have handled.

Interestingly some are copies of Giodi (swing-wing sample), some are copies of the Bruder models - the Lander for instance.
