I have a the same pattern on my bumperettes but don`t know what make they will fit on ? I don`t think it`s Buick as painted?

Take a real lock at the oil lines,I had that oil pressure problem in the 1970 s ,i took me a year to figure out what happend.After I had removed the oil line from the engine I could see a very small crack in the brass tube.

As "nzcarnerd" say it looks Buick yes it does,the removable top on the 1917 Buick are close but not the very right! Picture from "Seventy Years of Buick" by G.H Dammann

Looks close to Willys Knight 1920? https://car-from-uk.com/sale.php?id=78992

Here are a drawing from my 1956.But I think you have put the seal in wrong direktion in the outer tube close to the Dynaflow.

Looks to be to lock the spare tire.

The first Essex 1930.

When looking at this 1929 ser 77 Coupe the rear fender looks original? https://www.google.com/search?q=chrysler+car+1929+ser+77&tbm=isch&ved=2ahUKEwihp7Lg0P34AhUFmIsKHZevCTsQ2-cCegQIABAA&oq=chrysler+car+1929+ser+77&gs_lcp=CgNpbWcQA1CRCVjFD2COEmgAcAB4AIABY4gBgAKSAQEzmAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=tMzSYqH9G4WwrgSX36bYAw&bih=937&biw=1920&client=avast-a-1#imgrc=ajP7UQRdo0E3fM

Morris Minor 1000 probebly 1956-1971. https://en.wikipedia.org/wiki/Morris_Minor

Looks very much like a 1926-1927 Buick Master to me?

Sorry,can`t help you just becuse I found those pictures on the internet 7 years ago.You have to Google to find mor pictures!

Studebaker Commander 6 cyl.1938

The pattern more looks like 1916-1925.

At least not for 1911 Flanders car even if it`s that era!
