Some notes:
1. Notice the top frame. The older (pre-1930ish) top frames sometimes have that second bar coming off the main one which runs up from the door. Also notice that the canvas wraps back along the frame all the way to the door.
2. Wire frame wheels with very small drum brakes. Often times the drums are much bigger.
3. Rumble seat flips up at the back only. There is no front opening like on some.
4. Is that a manufactuer logo on the spare tire mount? Can't tell.
5. Chrome hinge on the hood. Many cars don't have that chrome accent.
I don't think it's a Ford Model A (pretty sure its not) and I don't think it's a Chevy roadster either. I think it might be something a little more unique, and probably pre 1930 or very early 1930s.
