Without a doubt!
Plus that spurious paint doesn't look very thick and as it is most likely some kind of "hobby paint" it should be fairly easy to correct. One option might be to remove the bad paint, repaint with an authentic paint. Then if you don't want a restored liner in an untouched shell, sell the liner as restored and add a suitable untouched period item. I believe you would still be in substantial profit.
Personally I think I would just remove the paint and make a decision then.
