bingo , bingo, bingo, *****sammons nails it***** 28 Pontiac roadster. That curly q body mark on the cowl panel is the tell tale........great work Sammons.
I was previously looking at closed cars that kept turning up in searches and they definitely did not have that specific body design. I have never looked into whether the other GM brands of the time the open car bodys were produced by outside suppliers
?
I know with Chevrolets, roadsters and phaetons bodys were not produced by FISHER BODY but by an outside supplier Hercules-Campbell for Chevrolet. The bodies are different and used different widths , hinges, latches, locks, rear rumble seat lids and angle of the quarter panels.
I know this from comparing my 1935 chevrolet standard series fisher bodied coupe and my 1935 Chevrolet standard series roadster with Hercules-Campbell body and a hell of a lot of research over two years.
Oakland was in business as part of GM from around 1914 until 1931 when it was discontinued as a seperate line . In 1926 GM created the cheaper pontiac and was part of the Oakland line. Oldsmobile in 1929--1930 created the Viking. Buick created the 1929-1930 Marquette. All of these sub models disappeared as the depression deepened, never to re-appear.
Only one that stayed was the Cadillac LaSalle from 1927 to 1940 .
