T-Mar,
I appreciate your response! Now that you mention "Metallic Dark Silver" I do remember this being the name of the color. You must be on to something here.
I am not familiar with the brand Kuwahara. What model Kuwahara would you suspect the Sport was taken from? Do you think you could scan and email me any of this information? I would absolutely appreciate any information you could provide.
Thanks so much for your help,
J B
