Of the slot car and slot racing groups on Facebook, one of my favorites is Slot Racing Oldschool, as a great deal of historical info keeps popping up there, much of it new to me.
As a US-based racer who primarily played with 1/24 cars, the rarities of the 1/32 world are largely new to me. This thread has been crafted from a series of posts made to the above-mentioned group made by Richard Hills, a contributing editor to Slot Magazine in the UK, who kindly granted permission for the re-use of his material. What you read below are largely the posts Richard made, with minor editing to his comments, along with the excellent pictures that relate to each post. The quoted texts are Richard's words.
Perhaps PdL has a chapter on Riko is his long-awaited book that he will post here to give a history if the Riko brand, which seemingly was the trade name of a company called Richard Kohnstam Limited.
