I believe an '03 should be a Custom, ASrts, & Historic case still.
Likely the former owner bought a newer guitar and swapped cases or just bought that case in order to keep the former.
I have a '98 that didn't come with an original case so I bought the C, A, & Historic case from a forum brother.
Personally I wish they had never changed that.
Hi - I have an LP from 03 with a Custom Arts and Historic case. So. They did quit shipping the historics with this case at the end of 03 then?
