To me it seems that the model is just prior the XT series was launched. Before the logo was limited to simply Hamer. However, I only know about Made in Korea (MIK) for this series. Never heard of a China one. Seems to be a rare bird in this regard. That series is known of being made of alder or any asian equivalent to it. I liked the SD Phat Cat pickups in them the most as opposed to humbuckers. It is worth upgrading pots and parts here and there. I have a MIK in Sunburst fitted with custom made strat style single coils in humbucker format. Love it. The guitar lovely resonates. The lighter wood calls for a bigger headstock than the USA originals to stand the string tension.
It is said that the series number doesn't tell anything. However, I believe the leading digit tells about the year of production. Anyone I came across telling about the age, it fitted with the leading digit. So mine is said being from 2001 and it starts with 1 with a 55k number following. Hence, I'd assume yours being from 2003. That would could closely fit with the renaming to XT later on.
Hope that helps.
