You're right that this is a 2003 model. The "F" in the SN indicates it was made by FujiGen in Japan, so that makes it a terrific buy at US$200 regardless of the model.
As far as what model it is, that's harder to say. I don't know of any 2003 model that matches these specs. Closest thing would be the RG170DX, but that was made in Indonesia. There are very few Japanese-made RGs with Strat-style trems. Most likely it's a mutt with a body from one model (perhaps an RG170?) mated to a guitar from a different model. The trem and the knobs are likely aftermarket parts.
It could be a decent guitar and at $200 even if it's junk you'll be fine. The neck alone is worth over half that.
I don't have a good feeling about it. Are there any Team J-Craft necks that aren't 5 piece? There have been fake Team J-Craft stamps for years. With that trem it makes it an even cheaper guitar so $200 is probably all it's worth, and not any kind of bargain.
