Just a thought here- I wonder if the color of the jack might have varied by what plant the car was built in, or some similar situation.

i don't know if this helps but i have a original jack for a 1937 with the original paint and it is green

 ???? ? ?I have seen two jacks for a 1940 Plymouth P10 4 door sedan? ?, first one had black on the base and the working mechanism.The second one which I bought has a? hunter green painted base with hunter green mechanism.? ?The man I bought it from has been very knowledgeable and helpful and says from talking to people up Hershey for years he is confidant that green is correct . I would appreciate knowing if indeed green is or perhaps both colors are or would be correct thanks for the info? happy PLY mouthing DANiel
