I have the exact shocks on one of my old Atlas cars, the YM-34. I don't think that the shocks are really any one companies property. I would say (just a guess) that several companies bought variations of this shock to use on their own car. Like I said these are even blue, like on my Atlas. I believe that Kyosho did have a car with these on them at some point but I believe they used a different color. I would not be suprised that many companies used them, especially in Japan where there used to be many smaller companies that tried to release a car when the Touring Car thing first got going.
I will post a picture later.
