This is a shot in the dark.
I live in Salt Lake City, near Bonneville Salt Flats.
My wife inherited a 1929 Auburn Convertible that was converted to Steam and contains a White engine. The conversion was by Walter Deitchman.
We heard it ran on Bonneville. I believe Walter was trying to patent parts of steam generation and maybe proving concept with this vehicle. But I am guessing.
Do you know anyone that can assist in finding if it is of value or historic importance?
