Decipher a hull id..

[GTSR]

Does a hull ID break down into meaningful info, such as model year?

I am looking into a Seacraft that claims to have been "redone". It measures 20 ft(19'8''). It is 25 inches from the transom lip to the bottom of the hull(dead center). Is this the "normal height"? The drain holes are approx 16 inches from the bottom of the V. The transom has a well, most of the seacrafts I have seen do not have a splash well. Does this narrow down the model year? Is there a source to look at to see the original layout and floor pattern to see if the floor has been replaced/raised?

This is my first post and thank you in advance for your help.
