Here's the magazine cover, Model Car Science, July 64.
Very curious, because it doesn't say where the body comes from - seems to be an MCS project, from an article a few months earlier (March) about the Twister - actually a scale demonstrator presented by Ford for future dragster concepts! So not really a Thingie. That original article gives scale plans, so it had to be scratchbuilt. But the "motorizing" article talks about a two-part body, that looks like injected plastic - odd! It was motorized with a Revell chassis, along with a higher performance Kemtron, brass tube variant.
Haven't found the original vac-form body of this yet, but maybe DuBro. And it was perhaps made as a static model kit too...
