ESTIMATED VALUE

What N118JK might be worth

No type-level range

Exhibition, racing, research and limited-category aircraft (warbirds, replicas and former military types among them) are valued one by one, on their history and condition. Radar does not put a type-level range on them. Total time, condition, equipment and the completeness of the logbooks set what one is worth.
