This looks like the Roy "Multy" Aldrich Model T gow job. Multy ran at the very first Bonneville Nationals and many other events.
PETALUMA CA . Petaluma Blvd feed mill is behind the building still the same except CHET DICKSON is long gone..
I think it is a more recent photo. I just found a description saying that is the Ford Model T demonstration race in High River, Alberta.
