Hot Rods Duvall history question?

When did George Duvall start making his famous windshields?

 

The quick answer seems to be sometime around '35, as they were originally intended to fit '35 and '36 roadsters. If memory serves correct, the So-Cal Plating "delivery" usedthe prototype.

 

But was that in "35 or later? When was the Spencer roadster built?

 

The Spencer roadster was built a bit later, I honestly can't remember if it was just barely pre war or post. But he started on the So-Cal plating Delivery whn the first crop of '35's came out and finished it just after the introduction of the '36s, so kinda take your pick on a date, but somewhere in there.

 

Thanks for that, I'll have to do some more searching. If I find more I'll post.
