I think it's a health and safety issue. Some stupid brat might swallow one and sue them. I still have my collection of plastic glow in the dark luminous fish. made a mobile with them in the bedroom when I was a kid. Great, they were!
You don't get free gifts in Corn Flakes etc because Kelloggs (and others) follow a new code of practice which bans marketing directly to kids. You don't see Tony the Tiger et al these days for the same reason. You have to target the 'gatekeeper' (ie Mums) so you can have free recipes etc in packets but not anything that allows you to harness 'pester power'. Big problem for companies like Kelloggs because that has been a bedrock of their marketing for over a hundred years.
In the 50's before cheap plastic came along, Kelloggs corn flakes cardboard boxes were printed with parts for models like cars or buses which you cut round and glued together.
Crivens! I certainly do. As someone already said, I think it was in Ready Brek (Central heating for kids ). I remember it as "Some chicken, some neck" rather than Turkey. We had a few of then, but I can only remember the Churchill one. Ps, I only remember characters in the Beano or Dandy using the word "Crivens!" And you don't see cartoon characters with the word "TILT" on their eyeballs when they see something that gobsmacks them any more
Jings crivens, help ma boab you should go to Glesga then. http://www.scotranslate.com/translate/scottish/jings-crivens-help-ma-boab/3/3754#.WBHgGi197IU
They also did a set of cardboard cut out 3-D dog heads . I mounted them on a board. Still got them somewhere, I'm sure.
I was lucky being the youngest of three sons, my two older brothers had a fantastic meccano collection and I learned how to build the models and in the set they had some electric motors. I learned so much from them. They used to make those Keil Kraft balsa wood planes and I did the same and they had a couple of ED Bee 1cc diesel/ether powered engines. Those were the days, annoying the neighbours firing up the engines with propeller attached and fixed in the vice in my Dad's shed. No health and safety in those days, flicking the propeller and hoping you get your finger out the way quick enough when it fired up at high revs and noise.
Did you ever have a Jetex motor? I kind of mini-rocket motor for models. It was a young pyromaniac's delight ...
Jetex powered rockets that actually worked though I was a little wary of the solid fuel pellets rattling around in ones pocket. Parents didn't seem too perturbed by it all. Meccano well yes I had some but 20 or so years later my elder brother took it all into "protective custody" in my absence and mixed it all with his. Still hoarding somewhere the tight fisted pensioner that he is.
Webra engines seem to ring a bell with me....the heady fumes of the ether mix whilst attempting refuelling...
