Technical Decode 51 convertible

Hi I have a 51 ford convertible and would like some help to decode the cowl number. it must be an earlier 51 as it’s stamped into the cowl.
number is
SP76 FK 4A 8047C
I know that SP means built at Sait Paul and 4A means built January 4th.
76 is convertible
Is FK the paint?
Need to know the colour.

looks like someone screwed up with the last number as it has an X through it.

serial number is
B1SP107811

Thanks in advance
Dave

 

F Greenbrier Metallic body color (convertible only)
K Blue Green/Black trim color (convertible only)

 

Hey thanks for that Squirrel.
Much appreciated.

so if I wanted to return my vert to original it wouldn’t be the two tone that it is now hey?
Do you think it would even have the crestliner type external trim sweeping up from the fenders to the rear?

 

I don't know the answers to those questions...all I have is a book that has a lot of paint/trim codes in it.

There probably are some more knowledgeable shoebox Ford guys who might know that, but I don't know where they are.
