R. Dakin & Co., 1986 - My First Dinosaur Toy Collection

(Complete?) collection of dinosaur toys, made by R. Dakin & Co., 1986

To be young again. I just posted an inquiry on The Dinosaur Toy Forum (the official forum of The Dinosaur Toy Blog) regarding the above pictured vinyl dinosaur figures I got when I was only three or four years old. These things are adorable, and I'm sure are what inspired what has been a life-long hobby of collecting dinosaur (and other extinct and extant animal) figures.

These cartoonish depictions are clearly based on known species, and given the diagnostic characters they posses, I imagine we are looking at (back row, left to right) Apatosaurus, Saurolophus, Spinosaurus, (front row, left to right) Stegosaurus, Ankylosaurus, and Monoclonius. I particularly like the fact that they went for less well known (at the time) species like Monoclonius and Spinosaurus, rather than Triceratops and Tyrannosaurus.

So, now the question: does anyone know anything about these figures? The only identifying feature on them is an inscription on each figure that reads "(c) R. Dakin & Co., 1986". Google search results haven't yielded a lot of clues, but if anyone else out there has ever seen these figures or knows anything about them (particularly if I have a complete set), I'd appreciate the information.

Thanks!
