Welcome to the Phorum!
We do not have anything on that unit in our digital library. There is a Sam's Photofact schematic with that chassis number available from the Sam's website. https://samswebsite.com/en/photofact/det.../id/114668
I think it was likely a 1971 model introduced in Autumn of 1970. I found a number of newspaper advertisements for it in October 1970. This example had a selling price of $365 (about $2640 in 2025 dollars).

By October of 1973 it was selling for $229. https://www.dropbox.com/scl/fi/hqqdsymf3...8cf&dl=0By the time it was a give away for a car sale in 1977 it was probably on liquidation sale. I can't explain the late patent date.
