Decoding Vin & engine numbers

I have recently purchased a three-owner, mostly original '55 Roadmaster vonvertible with 79K miles on it. It's in superb condition and is rust-free. The colors are Dover White with a red interior and runs like a dream. The top, top mechanism and seats have been restored to original specs.

I am new to Buicks and would love to be put in contact with someone or purchase a publication that can decode the mysterious numbers.

Thanks
Matt
