Port of Oakland Archives: photographs from 1932-1934 of the Vance Flying Wing
I am looking for photographs of an unusual airplane, usually called the Vance Flying Wing, that was built at Oakland Municipal Airport in 1932.
There are references to the airplane, its creator Claire Vance, and his company, the Vance Aircraft Company, in the Port of Oakland Board Minutes from 1932, 1933, and 1934.
I found a website (https://dmairfield.com/people/vance_ck/) that has two photographs of the Vance Flying Wing that indicate that the source is the "Port of Oakland Archives". Therefore I expect that there are at least two, and possibly more, photographs of the airplane in the Port of Oakland's historical archives.
I would be willing to pay reasonable costs for the relevant part of the Archives to be searched and for high resolution scanned images of any quality photographs of the airplane that are found. Drawings of the airplane would also be interest to me.
Please note that I am looking for the photographs for a personal project and I do not have any commercial intentions.
