Numbers off of my recent purchase: 1940 Series 51 4 dr turing sedan

Ok, here are the numbers off of the Data Plate

Style: 40-4519

Body#: 39402

Paint: 551

Trim: 810

Off of the engine directly behind the carburetor: 8 and a 31

Off of the engine a little further behind the carburetor ( but distinctly separate form the ones above) : 1330805-2

I know the paint color is not original or correct for the 1940 year, the data plate states Flint , Mich.

Style: 40-4519

Body#: 39402

Paint: 551

Trim: 810

4519 = Fisher body style number (Buick model 51)

4 = Buick

5 = Series 50 (Super)

19 = 4-door touring sedan, 6-passenger

39402 = body number, 39402th 4519 built at Flint, MI

The lack of a plant code indicates the body was built at Flint. All the body tags say Flint, even the ones on cars built at South Gate (plant code C) and Linden, NJ (plant code L).

Paint 551 = two-tone, Monterey Blue Metallic lower and Silver French Grey Metallic upper

Trim 810 = Tan Bedford Cord (2 Tone), available on models 51, 56S

Thanks Sean.... I think I made another rookie mistake with the numbers I gave that were on the engine. I believe that I mistakenly cited a part number. I did not get the numbers from the location on the engine that the owners manual said they would be located. I am going to the right place today to record the correct ones.
