Littlewoods Catalouge, that takes me back, mine was sort of a dual thing with Index with both going the way of the Dodo once Amazon became a thing, last thing I think I got from there was my Airhogs plane, a air motor powered uncontrolable fast moving thing that far surpassed it's supposed distance resulting in me having to chase it through several streets on one occasion as it decided to leave the playng fields.
