Whilst Looking At Streamline Cars,

I came across this one,

a concept car and trailer, there are no factory markings on the car, but looking at the number plate it was road worthy,

so I am guessing it was home built by, also a guess, the guy getting out of the car, 

there is a thought that it was built by Angelo R. Noble of Guadalupe, California, but I have not been able to find out more than that, my thought is however how many other cars must have been built, that have since being finished like this one vanished with just a picture or two of them remaining?
