John Zink Trackburner with Boeing turbine power. Front suspension appears to be Lotus 18. Looks like Dan Gurney aboard. Maybe '63-64 ? Front bodywork has a BRP look about it....
Another one bites the dust. I think it was actually built in 1962 although it ran at Indy for consecutive years.
I think the chassis could have been a bit more Lotus 18 than just the front suspension, although nobody is quite sure. Here's a photo of the rear, and lo and behold it's the Lotus rear bodywork.
