Factory Options

[thehermit]

Gang, Just a stranger here but am wondering about different factory options that may have been available on some of the 20' models. I am the very happy new owner of a 1974 SF 20 (purchased from MassBass via the site) . It does not have the unique non-skid pattern on the deck some like other 74's in the gallery. Also the fuel tank is in the console rather than under the deck. I could go on to mention that the rubrail is stainless instead of the black and the "SeaCraft" hull stciker is black letters on a white background instead of just letters on the hull. Were these just different options availabe for the original buyers to choose from or should I be taking a closer look at that serial numebr to confirm the year of the boat?
Thanks
Great site-look forward at being around for a while.
