Default Classic VIN Help

I'm trying to research my late grandfathers 1951 pan head. VIN #51FL5321. I'm not sure where to start, I have looked on other sites and seem to know that it was a 74 cubic inch motor, sport solo. Just by the pictures I have. I also have the original bill of sale.
I’m looking for ANY info you guys can give me, or even point me in the right direction.
Thanks!

New Info: It looks as though it may have been sold in Florida.
