What model is this?

I inherited my father-in-law's Gator 4x2. I guess that it was purchased in the early 2000s.

I have no documentation on it, so I don't know what model it is. The decal on the cargo bed just says Gator 4 X 2.

I DO have the PIN from the sticker on the back chassis. It is W004X2X072531

Is it possible to determine the model and year from this?

Any info would be greatly appreciated.

Thanks!
